MIL-PRF-15733/49K
Radiographic inspection (applicable to -0001, conformance inspection only): Following group A inspection, 100
percent of each lot of filters shall be subjected to radiographic inspection as follows:
Filters shall be X-rayed in one plane at 90-degree rotation (perpendicular to the filter longitudinal axis). Any
evidence of poor capacitor mounting or uneven soldering of capacitor to case shall be cause for rejection.
Rejected units shall be dissected and examined for poor workmanship or uneven soldering. Magnification
during visual examination shall be two-power minimum. Any defects noted shall require corrective action prior
to acceptance of any future lots.
Seal: In accordance with MIL-PRF-15733.
Capacitance to ground: In accordance with MIL-PRF-15733 and table I.
Capacitance tolerance: +100 percent, -0 percent except -0010 shall be +150 percent, -0 percent.
Temperature rise: +25C, maximum.
Dielectric withstanding voltage: In accordance with MIL-PRF-15733 and the following:
Test voltage: 125 percent of rated voltage (-0001); 370 V dc (-0002); 200 V dc (-0005); and 200 percent of
rated voltage (-0003, -0004, -0006, -0007, -0008, and -0010) applied between terminals and case for 1 minute;
polarity of the test voltage shall then be reversed and the voltage shall be applied for 1 minute.
Insulation resistance: In accordance with MIL-PRF-15733; the following details and exceptions shall apply:
Test temperature: +25C.
Test potential: Rated dc voltage or 100 V dc whichever is less.
Insulation resistance shall be not less than:
Dash numbers
Megohms
0001
500
0002 through 0005, 0008
100
0006, 0007, and 0010
1,000
Dissipation factor (-0008 and -0010): 3 percent maximum.
Voltage drop: See table I.
Overload: In accordance with MIL-PRF-15733. The following exception shall apply:
Measurements after test: Insulation resistance (+25) only 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):
Applied force: 5 pounds (-0001 through -0007)
4.5 pounds +3, -0 ounces (-0008 and -0010).
