MIL-PRF-15733/41H
Dielectric withstanding voltage: In accordance with MIL-PRF-15733. The following details and exceptions shall
apply:
Test voltage: 800 V dc for dash numbers 0001, 0002, 0003, 0005, and 0006.
250 V dc for dash number 0004
Test voltage shall be applied between either terminal and case. The test voltage shall be applied and
discharged through a resistance of at least 1 ohm per volt.
Barometric pressure (reduced): In accordance with MIL-PRF-15733 except the test altitude shall be 80,000 feet
(0.83 inch of mercury).
Insulation resistance: In accordance with MIL-PRF-15733. Insulation resistance measured between either
terminal and case shall be at least:

Voltage drop: In accordance with MIL-PRF-15733 and table I.
Transient voltage (not applicable to -0004): Filters shall withstand the transient over voltages specified in
MIL-STD-704 for 400 hertz ac systems. The following details shall apply:
Transient application: The output load shall be removed and the input voltage shall be stepped form 115 V rms
to 180 volts within 20 milliseconds of removal of the load. The step from 115 to 180 volts shall be
accomplished with a rise time of less than 60 milliseconds. The 180 volts shall be maintained for 100
milliseconds minimum. This cycle shall be repeated 10 times.
Measurements at +25°C after test: Insulation resistance and insertion loss shall be measured and shall meet
initial requirements.
Terminal strength: In accordance with MIL-PRF-15733 and method 211, MIL-STD-202, test condition A (pull).

The force shall be applied in a direction parallel to the longitudinal axis of the filter. Slight deformation at the
solder tab shall be allowable provided no cracks, fractures or other damage to the terminal results from this test.
Flashpoint of impregnant or potting compound: In accordance with MIL-PRF-15733. Minimum allowable
flashpoint shall be 145°C.
Salt atmosphere (corrosion): In accordance with MIL-PRF-15733 and Method 101, MIL-STD-202; test condition A.
Shock (specified pulse): In accordance with MIL-PRF-15733 and method 213, MIL-STD-202; test condition I. The
following details and exceptions shall apply:
Mounting: Filters shall be rigidly mounted by the body.
