2-1. Capacitance
The capacitance is the ratio of the change in an electric charge according to voltage change.
Due to the fact that the capacitance may be subject to change with the measured voltage and
frequency, it is highly recommended to measure the capacitance based on the following
conditions.
2-1-1. Measure capacitance with voltage and frequency specified in this document.
Regarding the voltage/frequency condition for capacitance measurement of each MLCC model,
please make sure to follow a section “C. Reliability test Condition - Capacitance” in this document.
The following table shows the voltage and frequency condition according to the capacitance
range.
[The voltage and frequency condition according to MLCC the capacitance range]
Class I
Capacitance Frequency Voltage
1,000 pF 1 MHz ± 10%
0.5 ~ 5 Vrms
> 1,000 pF 1 kHz ± 10%
Class II
Capacitance Frequency Voltage
10 1 kHz ± 10% 1.0 ± 0.2 Vrms
> 10 120 Hz ± 20% 0.5 ± 0.1 Vrms
Exception* 1 kHz ± 10% 0.5 ± 0.1 Vrms
Capacitance shall be measured after the heat treatment of 150+0/-10℃
for 1hr, leaving at room temperature for 24±2hr. (Class II)
2-1-2. It is recommended to use measurement equipment with the ALC (Auto Level Control) option.
The reason is that when capacitance or measurement frequency is high, the output voltage of
measurement equipment can be lower than the setting voltage due to the equipment limitation.
Note that when capacitance or measurement frequency is excessively high, the measurement
equipment may show ALC off warning and provide a lower output voltage than the setting
voltage even with ALC option selected. It is necessary to ensure the output voltage of
measurement equipment is the same as the setting voltage before measuring capacitance.

MLCC Product Manual
2-1-3. Capacitance value of high dielectric constant (Class II) MLCC changes with applied AC and DC
voltage. Therefore, it is necessary to take into account MLCC’s AC voltage characteristics and DC-
bias voltage characteristics when applying MLCC to the actual circuit.
2-1-4. The capacitance is in compliance with the EIA RS-198-1-F-2002.
2-2. Tan δ (DF)
2-2-1. An ideal MLCC’s energy loss is zero, but real MLCC has dielectric loss and resistance loss of
electrode. DF (Dissipation Factor) is defined as the ratio of loss energy to stored energy and
typically being calculated as percentage.
2-2-2. Quality factor (Q factor) is defined as the ratio of stored energy to loss energy.
The equation can be described as 1/DF. Normally the loss characteristic of Class I MLCC is
presented in Q, since the DF value is so small whereas the loss characteristic of Class II MLCC is
presented in DF.
2-2-3. It is recommended to use Class I MLCC for applications to require good linearity and low loss
such as coupling circuit, filter circuit and time constant circuit.
2-3. Insulation Resistance
Ceramic dielectric has a low leakage current with DC voltage due to the high insulating properties.
Insulation resistance is defined as the ratio of a leakage current to DC voltage.
2-3-1. When applying DC voltage to MLCC, a charging current and a leakage current flow together at
the initial stage of measurement. While the charging current decreases, and insulation resistance
(IR) in MLCC is saturated by time. Therefore, insulation resistance shall be measured 1 minute after
applying the rated voltage.
2-4. Capacitance Aging
The aging characteristic is that the high dielectric (Class II) MLCC decreases capacitance
value over time. It is also necessary to consider the aging characteristic with voltage and
temperature characteristics when Class II MLCC is used in circuitry.

MLCC Product Manual
4-2. Caution before Mounting
4-2-1. It is recommended to store and use MLCC in a reel. Do not re-use MLCC that was isolated from
the reel.
4-2-2. Check the capacitance characteristics under actual applied voltage.
4-2-3. Check the mechanical stress when actual process and equipment is in use.
4-2-4. Check the rated capacitance, rated voltage and other electrical characteristics before assembly.
Heat treatment must be done prior to measurement of capacitance.
4-2-5. Check the solderability of MLCC that has passed shelf life before use.
4-2-6. The use of Sn-Zn based solder may deteriorate the reliability of MLCC.
4-3. Cautions during Mounting with Mounting (pick-and-place) Machines
4-3-1. Mounting Head Pressure
Excessive pressure may cause cracks in MLCC.
It is recommended to adjust the nozzle pressure within the maximum value of 300g.f.
Additional conditions must be set for both thin film and special purpose MLCC.
4-3-2. Bending Stress
When using a two-sided substrate, it is required to mount MLCC on one side first before
mounting on the other side due to the bending of the substrate caused by the mounting head.
Support the substrate as shown in the picture below when MLCC is mounted on the other side.
If the substrate is not supported, bending of the substrate may cause cracks in MLCC.
4-3-3. Suction nozzle
Dust accumulated in a suction nozzle and suction mechanism can impede a smooth movement of
the nozzle. This may cause cracks in MLCC due to the excessive force during mounting.
If the mounting claw is worn out, it may cause cracks in MLCC due to the uneven force during
positioning.
A regular inspection such as maintenance, monitor and replacement for the suction nozzle and
mounting claw should be conducted.

MLCC Product Manual
4-4-2. Reflow temperature
The following quality problem may occur when MLCC is mounted with a lower temperature than
the reflow temperature recommended by a solder manufacturer. The specified peak temperature
must be maintained after taking into consideration the factors such as the placement of
peripheral constituent and the reflow temperature.
Drop in solder wettability
Solder voids
Potential occurrence of whisker
Drop in adhesive strength
Drop in self-alignment properties
Potential occurrence of tombstones
4-4-3. Cooling
Natural cooling with air is recommended.
4-4-4. Optimum solder flux for reflow soldering
· Overly the thick application of solder pastes results in an excessive solder fillet height.
This makes MLCC more vulnerable to the mechanical and thermal stress from the board, which
may cause cracks in MLCC.
·Too little solder paste results in a lack of the adhesive strength, which may cause MLCC to
isolate from PCB
· Check if solder has been applied uniformly after soldering is completed.
· It is required to design a PCB with consideration of a solder land pattern and its size to apply an
appropriate amount of solder to MLCC. The amount of the solder at the edge may impact
directly on cracks in MLCC.
· The design of a suitable solder land is necessary since the more the solder amount is,
the larger the force MLCC experiences and the higher the chance MLCC cracks.
Too Much Solder
large stress may cause cracks
Not enough solder
Weak holding force may cause bad
connections or detaching of the capacitor

MLCC Product Manual
4-6. Soldering Iron
Manual soldering can pose a great risk on creating thermal cracks in MLCC. The high temperature
soldering iron tip may come into a direct contact with the ceramic body of MLCC due to the
carelessness of an operator. Therefore, the soldering iron must be handled carefully, and close
attention must be paid to the selection of the soldering iron tip and to temperature control of the
tip.
4-6-1. How to use a soldering Iron
· In order to minimize damages on MLCC, preheating MLCC and PCB is necessary.
A hot plate and a hot air type preheater should be used for preheating
. Do not cool down MLCC and PCB rapidly after soldering.
· Keep the contact time between the outer termination of MLCC and the soldering iron as short as
possible. Long soldering time may cause problems such as adhesion deterioration by the
leaching phenomenon of the outer termination.

4-6-2. How to use a spot heater
Compared to local heating using a solder iron, heat by a spot heater heats the overall MLCC and
the PCB, which is likely to lessen the thermal shocks.
For a high density PCB, a spot heater can prevent the problem to connect between a solder iron
and MLCC directly.
· If the distance from the air nozzle outlet to MLCC is too close, MLCC may be cracked due to the
thermal stress. Follow the conditions set in the table below to prevent this problem.
·The spot heater application angle as shown in the figure is recommended to create a suitable
solder fillet shape.
24
W smsum: [ucmnrmscmmcs 25
MLCC Product Manual
4-6-3. Cautions for re-work
·Too much solder amount will increase the risk of PCB bending or cause other damages.
· Too little solder amount will result in MLCC breaking loose from the PCB due to the
inadequate adhesive strength.
·Check if the solder has been applied properly and ensure the solder fillet has a proper shape.
*Soldering wire below ø0.5mm is required for soldering.
4-7. Cleaning
4-7-1. In general, cleaning is unnecessary if rosin flux is used.
When acidic flux is used strongly, chlorine in the flux may dissolve into some types of cleaning
fluids, thereby affecting the performance of MLCC.
This means that the cleansing solution must be carefully selected and should always be new.
4-7-2. Cautions for cleaning
MLCC or solder joint may be cracked with the vibration of PCB, if ultrasonic vibration is too strong
during cleaning. When high pressure cleaning equipment is used, test should be done for the
cleaning equipment and its process before the cleaning in order to avoid damages on MLCC.

4-8. Cautions for using electrical measuring probes
·Confirm the position of the support pin or jig when checking the electrical performance of MLCC
after mounting on the PCB.
· Watch for PCB bending caused by the pressure of a test-probe or other equipment.
· If the PCB is bent by the force from the test probe, MLCC may be cracked or the solder joint may
be damaged.
· Avoid PCB flexing by using the support pin on the back side of the PCB.
· Place equipment with the support pin as close to the test-probe as possible.
· Prevent shock vibrations of the board when the test-probe contacts a PCB.
Not recommended Recommended
4-9. Printed Circuit Board Cropping
· Do not apply any stress to MLCC such as bending or twisting the board after mounting MLCC
on the PCB.
·The stress as shown may cause cracks in MLCC when cutting the board.
·Cracked MLCC may cause degradation to the insulation resistance, thereby causing short circuit.
· Avoid these types of stresses applied to MLCC.
[Bending] [Twisting]
4-9-1. Cautions for cutting PCB
Check a cutting method of PCB in advance.
The high density board is separated into many individual boards after the completion of soldering.
If the board is bent or deformed during separation, MLCC may be cracked.
Carefully select a separation method that minimizes the deformation of the PCB.

MLCC Product Manual
4-10. Assembly Handling
4-10-1. Cautions for PCB handling
Hold the edges of the board mounted with MLCC with both hands since holding with one hand
may bend the board.
Do not use dropped boards, which may degrade the quality of MLCC.
4-10-2. Mounting other components
Pay attention to the following conditions when mounting other components on the back side of
The board after MLCC has been mounted on the front side.
When the suction nozzle is placed too close to the board, board deflection stress may be
applied to MLCC on the back side, resulting in cracks in MLCC.
Check if proper value is set on each chip mounter for a suction location, a mounting gap and a
suction gap by the thickness of components.
4-10-3. Board mounting components with leads
If the board is bent when inserting components (transformer, IC, etc.) into it, MLCC or solder
joint may be cracked.
Pay attention to the following:
· Reduce the stress on the board during insertion by increasing the size of the lead insertion
hole.
· Insert components with leads into the board after fixing the board with support pins or a
dedicated jig.
· Support the bottom side of the board to avoid bending the board.
· Check the status of the height of each support pin regularly when the support pins are used.
Not recommended Recommended

4-10-4. Socket and / or connector attach / detach
Since the insertion or removal from sockets and connectors may cause the board to bent, make
sure that MLCC mounted on the board should not be damaged in this process.
4-10-5. Fastening screw
When attaching a shield on a board, the board may be bent during a screw tightening work
Pay attention to the following conditions before performing the work.
·Plan the work to prevent the board from bending
·Use a torque driver to prevent over-tightening of the screw.
· Since the board may be bent by soldering, use caution in tightening the screw.
4-11. Adhesive selection
Pay attention to the following if an adhesive is used to position MLCC on the board before
soldering.
4-11-1. Requirements for Adhesives
·They must have enough adhesive strength to prevent MLCC from slipping or moving during
the handling the board.
· They must maintain their adhesive strength when exposed to soldering temperatures.
· They should not spread when applied to the PCB.
· They should have a long pot life.
· They should hardened quickly.
· They should not corrode the board or MLCC materials.
· They should be an insulator type that does not affect the characteristic of MLCC.
·They should be non-toxic, not harmful, and particularly safe when workers touch the adhesives.
4-11-2. Caution before Applying Adhesive
Check the correct application conditions before attaching MLCC to the board with an adhesive.
If the dimension of land, the type of adhesives, the amount of coating, the contact surface areas,
the curing temperature, or other conditions are not appropriate, it may degrade the MLCC
performance.

MLCC Product Manual
4-11-3. Cautions for selecting Adhesive
Depending on the type of the chosen adhesive, MLCC insulation resistance may be degraded.
In addition, MLCC may be cracked by the difference in contractile stress caused by the different
contraction rate between MLCC and the adhesive.
4-11-4. Cautions for the amount of applied adhesive and curing temperature
·The inappropriate amount of the adhesive cause the weak adhesive strength, resulting in the a
mounting defect in MLCC
· Excessive use of the adhesive may cause a soldering defect, loss of electrical connection,
incorrect curing, or slippage of a mounting position, thereby an inflow of the adhesive onto a
land section should be avoided.
· If the curing temperature is too high or the curing time is too long, the adhesive strength will
be degraded. In addition, oxidation both on the outer termination (Sn) of MLCC and the
surface of the board may deteriorate the solderability.
4-12. Flux
4-12-1. The excessive amount of flux generates excessive flux gases which may deteriorate solderability.
Therefore, apply the flux thin and evenly as a whole.
4-12-2. Flux with a high ratio of halogen may oxidize the outer termination of MLCC, if cleaning is not
done properly. Therefore, use flux with a halogen content of 0.1% max.
4-12-3. Strong acidic flux can degrade the MLCC performance
4-12-4. Check the solder quality of MLCC and the amount of remaining flux surrounding MLCC after the
mounting process.
4-13. Coating
4-13-1. Crack caused by Coating
A crack may be caused in the MLCC due to amount of the resin and stress of thermal
contraction of the resin during coating process.
During the coating process, the amount of resin and the stress of thermal contraction of the
resin may cause cracks in MLCC
The difference of thermal expansion coefficient between the coating, or a molding resin may
cause destruction, deterioration of insulation resistance or dielectric breakdown of MLCC such
as cracks or detachment, etc.

MLCC Product Manual
4-13-2. Recommended Coating material
· A thermal expansion coefficient should be as close to that of MLCC as possible.
·A silicone resin can be used as an under-coating to buffer the stress.
· The resin should have a minimum curing contraction rate.
· The resin should have a minimum sensitivity (ex. Epoxy resin).
· The insulation resistance of MLCC can be deteriorated if a high hygroscopic property resin is
used in a high humidity condition.
· Do not use strong acid substances due to the fact that coating materials inducing a family of
halogen substances and organic acid may corrode MLCC.

5. Design
5-1. Circuit design
When the board is dropped or bent, MLCC mounted on the board may be short-circuited by the
drop in insulation resistance. Therefore, it is required to install safety equipment such as a fuse to
prevent additional accidents when MLCC is short-circuited, otherwise, electric short and fire may
occur. This product is not a safety guaranteed product..
5-2. PCB Design
5-2-1. Unlike lead type components, SMD type components that are designed to be mounted directly
on the board are fragile to the stress. In addition, they are more sensitive to mechanical and
thermal stress than lead type components.
5-2-2. MLCC crack by PCB material type
A great difference of the thermal expansion coefficient between PCB and MLCC causes thermal
expansion and contraction, resulting in cracks in MLCC. Even though MLCC is mounted on a
board with a fluorine resin or on a single-layered glass epoxy, cracks in MLCC may occur.
5-3. Design system evaluation
5-3-1. Evaluate the actual design with MLCC to make sure there is no functional issue or violation of
specifications of the finished goods.
5-3-2. Please note that the capacitance may differ based on the operating condition of the actual system
since Class 2 MLCC capacitance varies with applied voltage and temperature.
5-3-3. Surge resistance must be evaluated since the excessive surge caused by the inductance of the
actual system may apply to MLCC.
5-3-4. Note the actual MLCC size and the termination shape.

6-1. Storage environment
6-1-1. Recommendation for temperature/humidity
Even taping and packaging materials are designed to endure a long-term storage, they should
be stored with a temperature of 0~40°C and an RH of 0~70% otherwise, too high temperatures
or humidity may deteriorate the quality of the product rapidly.
As oxidization is accelerated when relative humidity is above 70%RH, the lower the humidity is,
the better the solderability is.
As the temperature difference may cause dew condensation during the storage of the product,
it is a must to maintain a temperature control environment
6-1-2. Shelf Life
An allowable storage period should be within 6 months from the outgoing date of delivery in
consideration of solderability. As for products in storage over 6 months, please check solderability
before use.
6-2. Caution for corrosive environment
As corrosive gases may deteriorate the solderability of MLCC outer termination, it is a must to
store MLCC in an environment without gases. MLCC that is exposed to corrosive gases may cause
its quality issues due to the corrosion of plating layers and the penetration of moisture.
