MIL-PRF-15733/58C
Insulation resistance: In accordance with MIL-PRF-15733. The following details and exceptions shall apply:
Test potential: Rated dc voltage.
Insulation resistance: Shall be not less than 700 megohms at +25°C and not less than 70 megohms at +125°C,
when measured between the case (ground) and all terminals connected together.
Voltage drop: In accordance with MIL-PRF-15733. Maximum voltage drop at +25°C shall be as specified in table I.
Insertion loss: In accordance with MIL-PRF-15733 and table I at 25°C and temperature extremes.
Terminal strength: In accordance with MIL-PRF-15733 and Method 211, MIL-STD-202; test condition A (pull),.
Applied force: 4.5 pounds.
Salt atmosphere (corrosion): In accordance with MIL-PRF-15733 and Method 101, MIL-STD-202; test condition B.
Shock (specified pulse): In accordance with MIL-PRF-15733 and Method 213, MIL-STD-202; test condition I.
Vibration, high frequency: In accordance with MIL-PRF-15733 and Method 204, MIL-STD-202; test condition D (20 G).
Moisture resistance: In accordance with MIL-PRF-15733. The following exceptions shall apply:
Measurements after 24-hour drying period:
Dielectric withstanding voltage: Voltage at 1.8 times rated dc voltage.
Insulation resistance and insertion loss shall meet initial requirements.
Life: In accordance with MIL-PRF-15733 and Method 108, MIL-STD-202. The following details and exceptions
shall apply:
Test condition D, (1,000 hours) for qualification inspection, test condition B (250 hours) for group C inspection.
Measurements after test at +25°C:
Dielectric withstanding voltage at 1.8 times rated dc voltage.
Insulation resistance and insertion loss shall meet initial requirements.
Voltage conditioning: Voltage conditioning shall consist of applying rated dc voltage to the part at +125°C. The
voltage shall be applied for a minimum of 250 hours. Charging and discharging current shall be limited within the
range of 50 to 150 milliamperes. The test circuit shall be in accordance with figure 2. E1 shall be continuously
monitored and if it falls below 95 percent of ET, the test shall be stopped and the defective part removed. Time
counted toward total test time shall be the time that E1 is greater than 95 percent of ET.
After the completion of 250 hours and while remaining at +125°C, the insulation resistance shall be measured and
shall be 70 megohms minimum.
