MIL-PRF-55514


Capacitors, Fixed, Plastic (or Metallized Plastic) Dielectric, DC or DC-AC, in Nonmetal Cases, Non-Established and Established Reliability, General Specification for FSC: 5910

This specification covers the general requirements for established reliability (ER) and non-established reliability (non-ER), (product level C), plastic (or metallized plastic) dielectric, fixed capacitors, enclosed in nonmetal cases intended primarily, in view of the limited long term moisture resistant characteristics, for use in potted or encapsulated systems, in blocking, filter, and by-pass applications. ER capacitors covered by this specification have failure rate levels (M, P, R, and S) ranging from 1.0 percent to 0.001 percent per 1,000 hours. These failure rates (FR) are established at a 90-percent confidence level and maintained at a 10-percent producer's risk and based on life tests performed at +85°C. An acceleration factor of 5:1 has been used to relate life test data obtained at 125 percent, or 140 percent of rated voltage at +85°C, to rated voltage at +85°C. The product levels are based on catastrophic failures and failures occurring outside the degradation limits.
