MIL-PRF-87164 Capacitors, Fixed, Mica Dielectric, High Reliability, General Specification For \(See Notice 1 For Replacement Information\)This specification covers the general requirements for high reliability, mica dielectric, fixed capacitors for space, missile, and other high reliability applications. Capacitors covered by this specification may be used in critical applications where the utmost in stability and dependability is required and where variations in capacitance with respect to temperature, voltage, frequency, and life cannot be tolerated \(see 6.1\). An acceleration factor of 25:1 has been used to relate life test data obtained at 150 percent of rated voltage at rated temperature to rated voltage at rated temperature.

1.2.1.3 Voltage. The rated voltage for continuous operation at +125�C is identified by a single letter as shown in

table II.

1.2.1.4 Capacitance. The nominal capacitance value, expressed in picofarads (pF) is identified by a three-digit

number; the first two digits represent significant figures and the last digit specifies the number of zeros to follow.

When the nominal value is less than 10 pF, the letter "R" shall be used to indicate the decimal point and the

succeeding digit shall represent a significant figure. For example, 1R0 indicates 1.0 pF.

1.2.1.5 Capacitance tolerance. The capacitance tolerance is identified by a single letter in accordance with table

III.
