Voltronics has been supplying high performance multi-turn trimmers
since 1963. Our range of trimmers are suitable for applications that
require high precision, mechanically stable with a high tolerance to
vibration and shock. Our success is based on a unique sealed, non-
rotating piston design that has become one of the designers preferred
choices for demanding applications.
As well as our extensive range of standard products we are able
to design and manufacture customized products for our specialty
customers. In addition we are able to offer a range of half turn
trimmers suitable for less stringent applications, but still providing good
stability and voltage handling capabilities.
For more than 30 years Voltronics has been partnered with leading
MRI manufacturers, supporting them with the highest quality
non-magnetic components. This has grown from just supplying
trimmer capacitors to now include a broad offering of non-magnetic
components focussed on MRI applications.

Washing Instructions:
The J-Series trimmer capacitors can withstand cleaning cycles up to 10 PSI and have been used by customers for more than a decade in
many diverse environmental conditions. Without knowing your particular washing or cleaning environment, we
recommend these basic guidelines:
1) Water wash or isopropyl alcohol cleaning agents are acceptable providing that baths are clean and uncontaminated.
For maximum effectiveness, the cleaning process should occur immediately after soldering.
2) Either brush or spray methods are acceptable.
3) * Drying out components with forced hot air is highly recommended.
4) Also, we do recommend turning the tuning screw 3 or 4 complete revolutions prior to arriving at the final “set.”
* If a water wash process is used and water does get inside, we recommend that the parts be heated above 100C for a minimum of 15
minutes, so that the water evaporates. After this, the rotor should be turned 1-2 times to redistribute the internal grease.

configurations this trimmer capacitor is an ideal replacement for
expensive sapphire dielectric trimmers. Applications include tuning
and impedance matching of high frequency, and high power
amplifiers especially where small size and high performance are
critical requirements.
The Only Internally-Sealed HV PTFE Trimmers
Voltronics’ concentric ring PTFE dielectric trimmer capacitors are
designed for use at frequencies up to 1.5 GHz. They are ideal
for HIGH VOLTAGE applications. The solid internal PTFE dielectric
prevents ionization, a major advantage in space, high altitude and
high voltage applications. The unique internal O-ring seal makes
wave soldering and vapor degreasing possible without the need to
attach a separate cap.
Available in two styles:
“A_HV” Series - Solder sealed ceramic body. “E_HV” Series - Epoxy
sealed plastic body.
The Voltronics A4 Series unique design using minimal parts
simplifies the manufacturing process to effect one of the most
economical high performance trimmer capacitors available in the
industry. The Voltronics A4 Series also features a high reliability
solid dielectric, positive tuning stops and up to 5 full turns of linear
tuning in the shortest length of any similar trimmer capacitor.

Voltronics “P” line of sapphire subminiature trimmer capacitors is
unique in design. The trimmers have a high Q, zero temperature
coefficient, and are internally O-ring sealed to keep out flux and
cleaning fluid. Yet, sizes are the same as the MIL unsealed styles.
The tuning screw does not move in and out, and RF current does
not run along it. Sapphire is ideal for precision trimmer capacitors.
Its dielectric constant is extremely stable and the dielectric loss is
below 0.0003 over frequencies up to 10GHz. Sapphire is chemically
inert, totally moisture resistant, and mechanically strong.
Other features include:
High Q, low temperature coefficient, and internal seal
Low self-inductance for use to 10 GHz
Interchangeability with unsealed designs
Long life, no measurable tuning noise

The PC17 styles are the only vertically mounted glass trimmers in
MIL-C-14409D.
Voltronics “S” Series are up to 40% shorter with 25% more range
than any other sealed standard glass RC. trimmers. The use of
Voltronics’ unique non-rotating piston design provides linear tuning,
high “Q”, long life, and high self-resonant frequencies. The O-ring
seal assures protection up to 40 p.s.i. against dust, moisture, flux,
solder, and cleaning solvents.
Glass and Quartz Trimmer Capacitors S Series
- Smallest Sealed Glass Trimmer Capacitors
Design Features
The unique Voltronics non-rotating precision trimmer capacitor
design offers the following advantages over conventional rotating
types:
Linear tuning with no reversals
A true high frequency device with high Q’s, low RF
losses, low constant inductance and high self-
resonant frequencies
A superior seal because the screw head and O-ring
do not move in and out
Greater life -10,000 cycles minimum
Much smaller sealed MIL sizes
Ability to provide extended metal or plastic shafts
General Specifications
(where not specified on detail pages)
Dielectric
The dielectric is a tube which has been precision drawn in a vacuum
so that its inner diameter is held within ±0.0002”. The choices are:
1. Annular Band Glass: A solid tube of a specially selected
formulation of glass which is metallized on the outside.
2. Embedded Band Glass: Two tubes of glass fired together
with a metallized silver band embedded between them.
The inner tube is only 0.005” thick to provide much higher
capacitance values.
3. Quartz: A pure-grade silicon oxide offering higher Q and
voltage ratings in each size with the trade-off of lower
capacitance and higher cost.

H Series - Extended Range Glass Trimmer Capacitors TF Series
- Vertical P.C. Mount Glass Trimmer Capacitors
The “H” Series increases the standard maximum capacitance values
of Voltronics’ glass trimmer capacitors by almost 100%. This is
achieved by a new and unique technique which makes the wall of
the inner glass tube thinner than was previously possible.
General specifications for the “H” Series are the same as those of
stan¬dard embedded band glass trimmers (see Page 18) with the
following exceptions:

metal tips affect tuning.
Pre-Set Trimmers
Every trimmer in this catalog can be set at a fixed value by
Voltronics. This saves you the labor of setting the trimmer and
can replace a fixed capacitor. If any part of the circuit drifts with
temperature or time, the trimmer can be tuned. This will save not
only initial set-up time, but will allow tuning without changing fixed
components.
Voltronics trimmers are as stable as fixed capacitors and many are
less expensive!

For a differential trimmer capacitor, the capacitance of one element
increases while the other element decreases, with the sum remain-
ing approximately constant.
Both elements of a split stator trimmer tune at approximately the
same rate.

Precision Microwave Cavity TunersDRO - Microwave Tuners For Dielectric Resonator
These precise tuners provide fine, stable adjustments to microwave
components such as cavities, DRO’s, wave guides and filters. Appli-
cations as diverse as space telemetry to supermarket door openers
use these products. The self-locking slots in the threads together
with the fine pitch provide reliable, permanent settings. They elimi-
nate the loose fits and low resolution of standard threads. Tuning is
smooth with controlled torque and no noise. Bushings, rotors and
dielectric rods may be purchased separately. The DRO tuners are
sealed either with an O-ring or by a true hermetic solder seal. The
many versions of screw tuners are either entirely metallic or with
dielectric rods of sapphire, alumina or quartz.
Tuning Element Taps
Fluted taps are offered for each part because the thread sizes are
fine and non-standard.

Dro Tuners
The Voltronics DRO Tuner design is based upon the proven tuning
mechanisms of its trimmer capacitors. The parts have O-ring sealed
front ends, long life, positive stops and low loss. The tuners have
up to 10 full turns of resolution. The disk diameter (”A” Dim.) can
be modified to meet your requirements. The hermetically sealed
parts have high temperature solder joints. When soldered into your
case, there is a hermetic barrier to the inside of your cavity. The
part’s O-ring seal keeps moisture and other contaminants from get-
ting inside the tuner.
New Designs
Voltronics continues to develop new products for microwave tuning.
Sizes and materials can be modified on most of the parts shown
here. Call the factory with your requirements.

Increasing magnetic resonance applications caused Voltronics to
launch an active engineering effort in this field years ago, one that
continues today. Due to the severe non-magnetism requirements in
these industries, we use only materials that exhibit no measurable
magnetism. Commercial brass and plating materials are not accept-
able. Our strict traceability and testing regimes insure this essential
parameter.
Most of our trimmers are internally sealed so that they withstand
immersion in flux and solvents without leaking. Most of our non-
magnetic trimmers have been used and tuned at temperatures as
low as 4K. Many of our selection of trimmers have been developed
for specific customer needs – let us design a high performance trim-
mer for your application.

The V9000 trimmer capacitor is a unique design: truly sub
miniature at just 0.64” in length, but offers the highest working
voltage rating, of 2kV and capacitance value, up to 12pF, available
in its size. Using a Sapphire dielectric, for its ideal dielectric
constant, it is extremely stable, is chemically inert, moisture
resistant and mechanically strong. Recently launched, additional
features are still under development, contact Voltronics for our

Recommended Procedure for Hand Soldering
Chip Capacitors
Equipment: Weller Ec-2001 soldering system
(42 watt) or equivalent (1/8” tip) for 11 Series,
(1/4” tip) for 25 Series or (3/8” tip) for 38 Series
310 ± 10 degrees C tip temperature
Solder: Sn60/Sn62/Sn63
Flux: Alpha 611 type RMA or equivalent
Cleaning Solvents:
2-propanol or commercial defluxing solvent
Procedure:
1. Preheat chip and stripline to 100-120°C for a minimum
of one minute. If solder other than the above is used,
preheat to within 50-70°C of reflow temperature.
2. Dip chip in flux for 2-3 seconds, or apply flux to chip and
stripline area. Apply solder paste if necessary.
3. Place iron on stripline for three seconds to preheat, then
move slowly to contact chip for approximately four
seconds to effect reflow.
4. When reflow is achieved, withdraw ¡ron slowly, allow to
cool naturally.
5. Clean area thoroughly, with 2-propanol or other defluxing
solvent. If possible, use ultrasonic cleaning for these steps.
6. Inspect solder fillet for coverage and defects.

The quality system is approved to MIL-l-45208 & 10001.
All parts are 100% thermal stress tested.
Attachment Methods
All parts are constructed to be compatible with commonly used
industry methods. Reflow soldering, wave soldering, vapor phase
soldering (“S” termination) and conductive epoxy (“R” termination)
may be used.
Cleaning
Chip capacitors can withstand commonly used cleaning agents
such as water, alcohol, and degreaser solvents. Ascertain that no
flux residues are left on the chip surfaces and no flux is trapped
under the chip. Flux residue will degrade Q, insulation resistance
and reliability.
Shelf Life
Capacitors will be solderable for a minimum of one year from date
of shipment if properly stored in the original packaging. Dry nitro
gen storage is preferable for longer periods.
Precautions
The rate of heating and cooling must be controlled to preclude
thermal cracking of the devices. Processes, heating or cooling,
should not exceed a rate of 20000 per minute. Spikes must not
exceed 100°C maximum for any solder operation. Avoid forced
cooling or contact with heat sinks, such as conveyor belts, metal
tables or cleaning solutions, before the chips reach ambient tem
peratures.
Why Rounded Corners?
Rounded corners provide uniform termination on these MLC
products. The greater surface area improves solder attachment and
provides a more uniform adhesion to the board. Rounded corners
also reduce the chance of tomb-stoning and mechanical thermal
shock types of stress.

Non Magnetic Diodes
In support of our magnetic resonance customers around the
world, Voltronics now offers a comprehensive line of non-magnetic
diodes. With our ISO9001 approved partner, Voltronics wants to be
your diode design partner for your future unique needs and your
reliable supplier of your current requirements. Our comprehensive
capabilities include PIN diodes, dual diodes, Schottky diodes, and
more. When your application requires high performance non-

Total junction capacitance plus package capacitance, measured
with an RF source voltage less than or equal to 71 mV RMS at 50
MHz and no DC bias, shall not exceed 3.5pF.
Q equal to or greater than 1,000.
Thermal resistance not to exceed 60°C / Watt
Maximum junction operating temperature shall be 125°C
IRMS 100 milliamps maximum
Saturation Current Less Than 50 milliamps
Minority Carrier Lifetime 24 nanoseconds (nominal)
Non Magnetic Hardware
Due to the severe non-magnetism requirements in the magnetic
resonance industries, we use only high purity metals that exhibit
no measurable magnetism. Commercial brass is simply not
acceptable for these applications. Our strict traceability and testing
regimes insure this essential parameter.
We can offer sizes, styles, and lengths beyond those shown in the
tables on these pages – such as Cheese Head, Round Head, and
set screws. We also offer flat washers to complete your needs.
Pan Head Flat Head
Coils also require inserts, pins, and other special
shapes that are custom-designed to satisfy the
specific requirements of the coil designer. The ability
to quickly and precisely supply custom designs is
part of our heritage and we are eager to sample our
high quality hardware based on your requirements.
As with the screws, washers, and nuts on this and
the preceding page, we use only high purity metals
that exhibit no measurable magnetism.
