SMD Sealed Type (PVG3/M4A_D01/G5)/Lead Sealed Type (PV32/12/37/36) Speci?cations 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).

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 should 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 should be used for all subsequent total resistance measurements.

Residual Resistance
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 should be measured with the measuring circuit shown in Figure 1, or its equivalent. The
adjustment rotor (screw) should 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 should count in determining whether or not a
contact 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) should be such that the adjustment rotor (screw) completes 1 cycle for 5 seconds minimum
to 2 minutes maximum. The test current used should follow the value given in Table 2 unless otherwise limited by
power rating.

The trimmer potentiometer should be subjected to each of the following temperatures (see Table 3) for 30-45
minutes. Temperature coefficient of resistance should be applied to the following formula.

The wiper should be set at approximately 40% of the actual effective-electrical rotational angle (number of turns). An
adequate DC test potential should be applied between terminal #1 and terminal #3. The voltage between terminal #1
and terminal #3, and the voltage between terminal #1 and terminal #2, should be measured and applied to the
following formula.
