MIL-PRF-81/5C
Fatigue:
C: Shall not exceed 12 percent or 0.75 pF, whichever is greater.
Torque: Not less than 1 ounce-inch nor more than 10 ounce-inches.
Life:
Qualification test: 1,000 hours at +85°C, 150 percent or rated volts dc with a peak alternating voltage of 50
percent of rated volts dc (100 hertz or less) superimposed.
Insulation resistance: Initial requirement.
Capacitance change: Shall not exceed ±8 percent of initial value or 0.5 pF, whichever is greater.
Group C life: Conditions and requirements are the same as that required for qualification.
Shock (specified pulse): Method 213 of MIL-STD-202, condition I (100 g's).
Vibration: Method 204 of MIL-STD-202, condition B (15 g's).
Capacitance change: Shall not exceed ±2 percent or 0.5 pF, whichever is greater.
DF: Shall be not more than 0.2 percent.
Dielectric withstanding voltage: 1,100 V dc, applied for 3 seconds ±2 seconds.
Insulation resistance: 10,000 megohms, minimum.
Moisture resistance: Method 106 of MIL-STD-202:
Insulation resistance: 10,000 megohms, minimum.
Capacitance change: Shall not exceed ±5 percent of nominal value or 0.5 pF, whichever is greater.
DF: Shall be not more than 0.5 percent.
Qualification inspection is not required.
Marginal notations are not used in this revision to identify changes with respect to the previous issue due to the
