MIL-PRF-87217 Capacitors, Fixed, Supermetallized Plastic Film Dielectric, Direct Current For Low Energy, High Impedance Applications, Hermetically Sealed In Metal Cases, High Reliability, General Specification ForThis specification covers the general requirements for high reliability, supermetallized plastic film dielectric, fixed capacitors, hermetically sealed in metal cases. Capacitors covered by this specification have a failure rate \(FR\) level established in accordance with MIL-STD-690. This FR level is established at a 90-percent confidence level and maintaned at a 10-percent producer\'s risk and, unless otherwise specified \(see 3.1\), is based on MIL-PRF-83421 life tests performed at maximum rated voltage at maximum rated temperature.
