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 capacitor may deviate from the
specified characteristics.
3. Cleaning
(1) 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.
(2) The total cleaning time by cold dipping, vaper
and ultrasonic washing (conditions as below)
method shall be less than 3 minutes.
(3) For ultra-sonic cleaning, the available
condition is as follows.
(2) Can not be soldered using the flow soldering
method. 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.

SMDSealedType/LeadSealedType Specifications and Test Methods
The following describes trimmer potentiometer testing conducted by Murata Manufacturing Co., Ltd. in accordance with MIL-R-22097 (Military specification
for variable resistors, non-wirewound) and MIL-STD-202 (Test methods for electronic and electrical component parts).

Item
Test Methods
Measure total resistance between the resistance element and 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 for all subsequent total resistance measurements.

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 clock-
wise limit of mechanical travel and measure the resistance between the contact arm and the corresponding end ter-
minal. During this test, take suitable precautions to ensure that the rated current of the resistance element is not
exceeded.

Residual Resistance
Contact resistance variation shall be measured with the measuring circuit shown in Figure-1, or its equivalent. The
adjustment rotor (screw) shall be rotated in both directions through 90% of the actual effective-electrical rotational
angle(number of turns) for a total of 6 cycles. Only the last 3 cycles shall count in determining whether or not a con-
tact resistance variation is observed at least twice in the same location, exclusive of the roll-on or roll-off points
where the contact arm moves from the termination, on or off, the resistance element. The rate of rotation of the
adjustment rotor (screw) shall be such that the adjustment rotor (screw) completes 1 cycle for 5 seconds minimum to
2 minutes maximum. The test current used shall follow the value given in Table-2 unless otherwise limited by power
rating.

1) PV-- series
The trimmer potentiometer shall be vibrated throughout the frequency range at the 20G level. A complete frequency
range, 10Hz to 2000Hz and back, shall be made within 15 minutes for a total of 4 sweeps in each of the three axis
direction for a total of 12 sweeps.

Vibration
2) PVF2 series
The trimmer potentiometer shall be subjected to vibration at 0.3 inch amplitude. The frequency shall be varied uni-
formly between the approximate limits of 10 Hz and 55Hz. This motion shall be applied for preiod of 2 hours in each
of 3 mutually perpendicular direction (total of 6 hours).
1) PV-- series
The trimmer potentiometer shall be shocked at the 100G (50G for PV22 and PV23series) level and shall be subject-
ed to 4 shocks in each of the three axis direction for a total of 12 shocks.
2) PVM4A---B01series
Shock
The trimmer potentiometer shall be shocked at the 100G level and shall be subjected to 3 shocks in each of the six
axis direction for a total of 18 shocks.
Full rated continuous working voltage not exceeding the maximum rated voltage shall be applied intermittently
between the terminal #1 and the terminal #3 of the trimmer potentiometer, 1.5 hours on and 0.5 hours off, for a total
of 1000±12 hours, at a temperature of 70±2°C (85±2°C for PV01 and PV37series, 50±2°C for PVF2series). The trim-
mer potentiometer shall be removed from the chamber, and maintained at a temperature of 25±5°C for 1 to 2 hours.
10 Temperature Road Life

The trimmer potentiometer shall be placed in a camber at a temperature of 125±3°C (150±3°C for PV12series)
250±8 hours without loading. The trimmer potentiometer shall be removed from the camber, and maintained at a
temperature of 25±5°C for 1 to 2 hours.
High Temperature Exposure
(Except for PVF2)
11
The trimmer potentiometer shall be placed in a camber at a temperature of -55±3°C for 1 hours without loading. Full
rated continuous working voltage not exceeding the maximum rated voltage shall be applied for 45 minutes. The
trimmer potentiometer shall be removed from the chamber, and maintained at a temperature of 25±5°C for approxi-
mately 24 hours.

Low Temperature Operation
(Only for PVF2 and
PVM4A---B01)
The trimmer potentiometer shall be placed in a camber at a temperature of -25±3°C (-55±3°C for PVM4A---
B01series) 48±4 hours without loading. The trimmer potentiometer shall be removed from the chamber, and main-
tained at a temperature of 25±5°C for 5±1/6 hours
1)PV-- series
Full rated continuous working voltage not exceeding the maximum rated voltage shall be applied with the circuit
shown in the figure. The adjustment rotor (screw) shall be continuously cycled through not less than 90% of effec-
tive-electrical rotational angle (number of turns), at the rate of 1 cycle for 5 seconds minimum to 2.5 a minutes maxi-
mum for total of 200 cycles.

2) PVG3, PVG5series
The adjustment rotor (screw) shall be continuously cycled though not less than 90% of effective- electrical rotational
angle (number of turns), at the rate of 1 cycle for 5 seconds minimum to 2.5 minutes maximum for a total of 50 (100
for PVG5) cycles, without loading.
3) PVF2, PVM4A---B01series
The wiper shall be rotated over 90% of the effective rotational angle without loading at a speed of 10 cycles per
minute, for 100 cycles continuously.
