Q+products have given rise to plenty of discussions since their launch.
The most frequently asked questions: What advantage do these products give us?
To whom may I sell them? And for which applications are they suitable?
Q+products
Benefits
1Optimized
construction
4High process
capability level
Internal structures of the products in the Q+products portfolio are
very different from conventional ones. For example, the wire connec-
tion between coil wire and component is not made with a conven-
tional solder joint, but by means of a welding process. Another exam-
ple is ferrite sleeves; compared with the conventional industry
article, the surface form is optimized and this considerably simplifies
the routing of lines.
Process capability is determined by means of familiar statistics and
describes the stability of a manufacturing process. A statistical eval-
uation by itself will not make a manufacturing process more stable,
however. This also depends on the added values of other Q+prod-
ucts.
3
Automation vs. partial automation / manual process
Increasing the degree of automation in the manufacturing process
changes the variance of process parameters positively by eliminat-
ing the influence of the operator. This also ensures even more effec-
tive process controlling.
Higher level
of automation
2AEC-Q 200
qualification
All Q+products are qualified in accordance with the AEC-Q 200. The
Automotive Electronics Council Qualification (AECQ) does not reflect
the qualification standard of the automotive industry in all cases, but
describes product quality very precisely only by means of a variety of
reliability checks.

6Production on
strictly defined
production lines
Additional quality controls can be carried out efficiently only if they
are used for previously evaluated production lines. Even two identical
manufacturing processes can have different results. So pro-
cess-based influences are difficult to generalize, which is why we
specially select and monitor the production lines.
5
Additional quality controls are geared specifically to the familiar, crit-
ical quality features of the individual Q+products. These features are
directly monitored, documented and qualified according to their re-
quirements in the appropriate manufacturing step.

quality controls
7
The market requires tough products. So we have already extended
the temperature range of Q+products ferrite sleeves to -55 °C /
+150 °C. We also aim to extend such increases in temperature range
to include all Q+products.

1000 cycles at operating temperature (according to the datasheet,
e.g. -40 °C / +125 °C). with an maximum dwell time of one minute.
Biased Humidity
1000 hours at 85 °C and 85 % RH without electrical stress
Operational Life
1000 hours at operating temperature minus self-heating tempera-
ture under electrical stress (rated current)
External Visual
Inspection of the device looking / construction, workmanship and
marking.
Physical Dimension
The mechanical dimension have to be in between the specification
Terminal Strength (SMD)
The parts will be stressed with a pull of force of 17.7 Newton for
60 seconds. The focus is on the soldering joint.
Resistance to Solvents
Three different kinds of solvent do not have any impact to the device
construction, marking and looking.
Mechanical Shock
Mechanical shocks shall not have any impact to the device construc-
tion or function. These shocks will be simulated 18 times, by a am-
plitude of 100 g’s for 6 milliseconds.
Vibration
Vibrations of 10 g’s in a frequency range from 15 up to 2000 Hz for
20 minutes shall not have any impact to the construction of the
device. This process will be done in 12 cycles for each of the Axis.
Resistance to Soldering Heat
A Reflow Oven Test for five times shall not have any impact to the
device
ESD
An Electrostatic discharge of 6 kV with direct contact, 12 kV, 16 kV
and 25 kV with air contact shall not have any impact to the device.
Solderability
Three different Soldering procedures will be gone through. In each
case an impact to the device and construction isn’t allowed.
Electrical Characterization
Parametrically test which shows in a summary the min, max, man
and standard deviation at room temperature as well as at min and
max operating temperature.
Board Flex
At surface mounted devices, an impact due to bending, flexing and
pulling forces shall be not be given.

Standards by Comparison
Although it might seem much better at the first sight, it doesn’t mean, that the industrial parts are less qualified than the Q+ Products. The
difference in here is the higher reliable requirements which we going to prove accordance to the AEC-Q 200. To show the difference, the
following table contrasts some main parts out of the industrial qualification standard of Würth Elektronik eiSos with the main necessary
qualification standards out of the AEC-Q 200.

Type definition of SMD ferrites WE-CBA
The special SMD chip bead ferrites can be put directly on the printed circuit board. They offer excellent anti-EMI properties and low
DC-resistance. Placed very close next to the interference source even with smallest size 0402, maximal impedance at 1000 Ω can
be reached.
High Speed:
“High Speed” SMD ferrites WE-CBA have lower impedance in the lower frequency ranges thus they have only a low attenuation
for fast signals.
Application e.g. USB 2.0, IEEE 1394, LVDS
Wide Band:
“Wide Band” SMD ferrites WE-CBA already show high impedance in low frequency range. Therefore they are wide band through
the whole spectrum.
Application e.g. control signals, RS232, RS422, DC/DC converter
High Current:
“High Current” SMD ferrites WE-CBA are designed for high current (over 1 A). The rated current refers to 40 K self-heating.
High current SMD ferrites are available in all three types (High Speed, Wide Band and High Frequency).
Application e.g. power supply, DC/DC converter
Advice: Pay attention for the use of SMD ferrites for high rated current >1 A and ambient temperature over +85 °C that the rated
current has to be reduced when temperature is above +85 °C (Derating).
The characteristic line in the right figure shows, that e.g. at +100 °C ambient temperature the maximal rated current has to add
up to only 60 % of the data sheet value, without an overload of the component.
Derating +85 °C
Derating +105 °C

Note
The ambient temperature when operating the WE-PD series of storage chokes at full current rating load should generally range from
-40 °C to +85 °C. The self-heating of the component must be taken into account at higher ambient temperatures in order that the
permissible solder joint temperature is not exceeded or the wire insulation damaged. The wire used can withstand a temperature of
up to +150 °C. The ferrite core itself may be used over a far greater temperature range (approx. -50 °C to +250 °C [Curie tempera-
ture]). However, in this case, the tolerance limits of the inductor may be exceeded due to the temperature dependence of permeability.

General:
All recommendations according to the general technical specifications of the datasheet have to be complied with.
The disposal and operation of the product within ambient conditions which probably alloy or harm the component surface
has to be avoided.
If the product is potted in costumer applications, the potting material might shrink during and after hardening. According-
ly to this the product is exposed to the pressure of the potting material with the effect that the ferrite body and termination
is possibly damaged by this pressure and so the electrical as well as the mechanical characteristics are endanger to be
affected. After the potting material is cured, the ferrite body and termination of the product have to be checked if any
reduced electrical or mechanical functions or destructions have occurred.
The responsibility for the applicability of customer specific products and use in a particular customer design is always
within the authority of the customer. All technical specifications for standard products do also apply for customer specific
products.
Washing varnish agent that is used during the production to clean the application might damage or change the charac-
teristics of the plating. The washing varnish agent could have a negative effect on the long term function of the product.
Direct mechanical impact to the product shall be prevented as the ferrite material of the ferrite body could flake or in the
worst case it could break.
Product specific:
Follow all instructions mentioned in the datasheet, especially:
The solder profile has to be complied with according to the technical reflow soldering specification,
otherwise no warranty will be sustained.
Wave soldering is only allowed after evaluation and approval.
All products are supposed to be used before the end of the period of 12 months based on the
product date-code, if not a 100 % solderability can’t be warranted.
Violation of the technical product specifications such as exceeding the nominal rated current
will result in the loss of warranty.
