1. Excellent solderability characteristics are
achieved via special plating techniques on each
termination.
2. Specially designed substrate prevents wicking of
flux onto the top of the part body.
3. Enlarged bottom termination enhance soldering
strength while reducing the nocessary land area
required promoting high-density PCB mounting.
4. Funnel shaped adjustment slot allows for in-process
automatic adjustment.
5. Flat surface is provided for smooth pick and place.
(PVZ3K only)
6. Heat-Resistant type is available. (PVZ3AxxxB01)
7. The standard position of driver plate is adjusted
at the center normally, but another position is
also available.

Before using other soldering conditions than
those listed above, please consult with Murata
factory representative prior to using. If the
soldering conditions are not suitable, e. g.,
excessive time and/or excessive temperature,
the trimmer potentiometer may deviate from the
specified characteristics.
(2) Flow slodering is available for PVA3 series.
For PVZ3A, PVZ3K and PVS3, do not use flow
soldering method (dipping).
If you use the flow soldering method, the
trimmer potentiometer may not function.
(3) The soldering iron should not come in contact
with the case of the trimmer potentiometer. If
such contact does occur, the trimmer
potentiometer may be damaged.
(4) Apply the appropriate amount of solder paste.
The thickness of solder paste should be printed
from 150micro m to 200micro m (PVZ3K series
should be printed from 100micro m to 150micro m)
and the dimension of land pattern should be
used Murata's standard land pattern at reflow
soldering. Insufficient amounts of solder can
lead to insufficient soldering strength on PCB.
Excessive amounts of solder may cause the
bridging between the terminals.
2. Mounting
(1) Use our standard land dimension. Excessive land
area causes displacement due to effect of the
surface tension of the solder. Insufficient
land area leads to insufficient soldering
strength of the chip.
(2) Do not apply excessive force (preferable 4.9N
(Ref.; 500gf) max.), when the trimmer
potentiometer is mounted to the PCB.
(3) Do not warp and/or bend PC board to prevent
trimmer potentiometer from breakage.
(4) In chip placers, the recommended size of the
cylindrical pick-up nozzle should be outer

3. Cleaning
(1) In case there is flux on the resistive element,
clean sufficiently by cleaning solvents and
remove all residual flux perfectly.
(2) Isopropyl-alcohol and Ethyl-alcohol are
applicable solvent for cleaning. If you use any
other types of solvents, please consult with
Murata factory representative prior to using.

■ Notice (Handling)
1. Use suitable screwdrivers that fit comfortably in
driver slot. We recommend the below screwdrivers.
* Recommended screwdriver for manual adjustment
VESSEL MFG. : NO.9000+1.7x30
(Murata P/N : KMDR080)
TORAY MFG. : SA-2225
(Murata P/N : KMDR070)
* Recommended screwdriver for automatic
adjustment
TORAY MFG. : JB-2225
(Murata P/N : KMBT070)
2. Don't apply more than 4.9N (Ref.; 500gf) of twist
and stress after mounted onto PCB to prevent
contact intermittence. If excessive force is
applied, the trimmer potentiometer may not
function.
3. For PVZ3 and PVA3series, please use within the
effective rotational angle.
The potentiometer dose not have a mechanical stop
for over rotation. In case out of effective
rotational angle, the trimmer potentiometer may
not function.
4. When using a lock paint to fix slot position,
please consult with Murata factory representative
prior to using to prevent corrosion and contact
intermittence.

Test Methods
Measure total resistance between the resistance element and terminals (terminals #1 and #3) with the contact arm
positioned against a stop. The positioning of the contact arm and terminal shall be the same for subsequent total
resistance measurements on the same device.
Use the test voltage specified in Table-1 for total resistance measurements. This voltage shall be used whenever a

Residual Resistanc
Position the contact arm at the extreme counterclockwise limit of mechanical travel and measure the resistance
between the contact arm and the corresponding end terminal. Then, position the contact arm at the extreme clockwise limit of mechanical travel and measure the resistance between the contact arm and the corresponding end terminal. During this test, take suitable precautions to ensure that the rated current of the resistance element is not
exceeded.
Contact resistance variation shall be measured with the measuring circuit shown in below, or its equivalent. The
operating wiper shall be rotated in both directions through 90% of the actual effective-electrical travel for a total of 6
cycles.
The rate of rotation of the operating wiper shall be such that the wiper completes 1 countin determining whether or
not a contact resistance variation is observed at least twice in the same location. The test current shall follow the
value given in Table-2 unless otherwise limited by the power rating.

Rotational Life
The wiper shall be rotated over 90% of the effective rotational angle without loading at a speed of 10 cycles per
minute, for 10 cycles continuously. The resistance value shall be measured after keeping the potentiometer in a
room for 10±5 minutes.
