1/ The complete type designation will include an additional digit to indicate style CV31 or CV32.
Dielectric withstanding voltage: Method 301 of MIL-STD-202. A dc potential of 2.2 times rated voltage applied
between terminals for 3 seconds ±2 seconds.
Temperature coefficient: Within the limits specified for the applicable characteristic.
Capacitance drift: Within 0.75 percent of initial step 1 measurement or 0.50 picofarad (pF), whichever is greater.
Terminal strength:
Pull test: Capacitor held by body and 4-pound-load applied to each terminal for at least 10 seconds.
Torque: Not less than 1 ounce-inch nor more than 6 ounce-inches.
Barometric pressure (reduced):
Method 105 of MIL-STD-202, condition D (100,000 feet).
Test potential: 100 percent of dc rated voltage.
