MIL-C-11693C, MILITARY SPECIFICATION: CAPACITORS, FEED THROUGH, RADIO-INTERFERENCE REDUCTION, DC (HERMETICALLY SEALED IN METAL CASES), ESTABLISHED AND NON-ESTABLISHED RELIABILITY, GENERAL SPECIFICATION FOR (05-OCT-1971) [S/S BY MIL-PRF-11693D]

MIL-C-11693C, MILITARY SPECIFICATION: CAPACITORS, FEED THROUGH, RADIO-INTERFERENCE REDUCTION, DC (HERMETICALLY SEALED IN METAL CASES), ESTABLISHED AND NON-ESTABLISHED RELIABILITY, GENERAL SPECIFICATION FOR (05-OCT-1971) [S/S BY MIL-PRF-11693D]., This specification covers the general requirements for established reliability (ER) and non-ER capacitors designed for operation with direct current (dc), paper, paper plastic, and plastic (extended foil) dielectric, radio-interference-reduction, feed-through capacitors, hermetically sealed in metal cases (see 6.6.2), for use primarily in broadband, radio-interference suppression application. Capacitors meeting the established reliability requirements specified herein have a maximum failure rate of 1.0 percent per 1,000 hours. This failure rate is established with a 90-percent confidence limit based on the life test parameters specified and are maintained at a 10-percent producer’s risk. 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.
