MIL-PRF-39001



Capacitor, Fixed, Mica Dielectric, Established Reliability and Nonestablished Reliability, General Specification for (w/Amendment 1) FSC: 5910

This specification covers the general requirements for established reliability (ER) and non-established reliability (non-ER), mica dielectric, fixed capacitors. The ER capacitors have a failure rate level (FRL) ranging from 1.0 percent per 1,000 hours to 0.001 percent per 1,000 hours. The FRL is established at a 90 percent confidence level. The FRL, identified by the applicable symbol specified in table V is referred to operational life at full rated voltage at +125°C or +150°C, as applicable. An acceleration factor of 25:1 has been used to relate the life test at 150 percent of rated voltage at rated temperature to rated voltage at rated temperature.
