MIL-PRF-81/12A
Torque: Not less than 0.2 ounce-inch nor more than 1.4 ounce-inches.
Shock (specified pulse): Method 213 of MIL-STD-202, condition I (100 g's).
Vibration, high frequency: Method 204 of MIL-STD-202, condition B (15 g's).
Capacitance change: Shall not exceed ±2 percent of nominal value or 0.5 pF, whichever is greater.
DF: Shall be not more than 0.2 percent for rated maximum capacitance 6 pF, 10 pF, and 20 pF, 0.3 percent
for 30 pF.
Dielectric withstanding voltage: A dc potential of 2.2 times rated voltage applied between terminals for 3
seconds ±2 seconds.
Insulation resistance: Shall be 10,000 megohms, minimum.
Fatigue: At a rate of approximately 20 cycles per minute for a period of 1 minute.

Torque: Initial requirement.
Life:
Qualification test: 1,000 hours at +85°C, 150 percent of rated V dc with a peak alternating voltage of 50
percent of rated V dc (100 hertz or less) superimposed.
Insulation resistance: Initial requirement.
Capacitance change: Shall not exceed ±8 percent of initial value or 0.75 pF, whichever is greater.
Group C life: Conditions and requirements are the same as that for qualification.
Moisture resistance: Method 106 of MIL-STD-202.
Insulation resistance: Shall be 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.
Marginal notations are not used in this revision to identify changes with respect to the previous issue due to the
