适用范围

This specification covers the general requirements for established eliability (ER), metallized plastic film dielectric, fixed capacitors, hermetically sealed in metal or ceramic cases. Capacitors covered by this specification have failure rate levels (FRL) established in accordance with MIL-STD-690. The reliability for each level is identified by a symbol in accordance with table I. These FRLs are established at a 90 percent confidence level and maintained at a 10 percent producer's risk and, unless otherwise specified (see 3.1), are based on life tests performed at maximum rated voltage at maximum rated temperature. Unless otherwise specified (see 3.1), anacceleration factor of 5:1 has been used to relate life-test data obtained at 140 percent of rated voltage at maximum rated temperature, to accelerated voltage (140 percent of rated voltage) at maximum rated temperature (see 6.1). A part per million (PPM) quality system is used for documenting and reporting the average outgoing quality of capacitors supplied to this specification. Statistical process control (SPC) techniques are required in the manufacturing process to minimize variation in production of capacitors supplied to the requirements of this specification.
