MIL-PRF-19978J, PERFORMANCE SPECIFICATION, CAPACITORS, FIXED, PLASTIC (OR PAPER-PLASTIC) DIELECTRIC (HERMETICALLY SEALED IN METAL, CERAMIC OR GLASS CASES), ESTABLISHED AND NON-ESTABLISHED RELIABILITY, GENERAL SPECIFICATION FOR (25 MAR 2003) [SUPERSEDING MIL-C-19978F]., This specification covers the general requirements for established reliability (ER) and non-established reliability (non-ER), direct current (dc), plastic or paper-plastic dielectric, fixed capacitors, hermetically sealed in metal or ceramic or glass cases. Capacitors meeting the established reliability requirements specified herein have failure rate (FR) levels ranging from 1.0 percent to 0.001 percent per 1,000 hours (see 1.2.1.9). These FRLs are established at a 90-percent confidence level and maintained at a 10-percent producer's risk and are based on life tests performed at maximum rated voltage and maximum rated temperature. An acceleration factor of 5:1 has been used to relate the life test data obtained at 140 percent of rated dc voltage at the applicable high test temperature to the rated voltage at the applicable high test temperature. This specification also covers removable mounting retainers for use with applicable capacitors (see 3.1). A part per million (ppm) quality system is used for documenting and reporting the average outgoing quality of ER capacitors supplied to this specification. Statistical process control (SPC) techniques are required in the manufacturing process to minimize variation in production of ER capacitors supplied to the requirements of this specification.【英文标准名称】:Aerospaceseries-Nuts,hexagonal,self-locking,withcounterboreandcaptivewasher,inheatresistingsteel,MoSlubricated-Classification:1100MPa(atambienttemperature)/315°C;GermanandEnglishversionEN2883:2009
