Description
MIL MIL-PRF-20L covers the general requirements for established reliability (ER) and non-ER,temperature compensating, fixed capacitors for use primarily where compensation is necessary for circuitapplications due to temperature changes, in bypass and coupling applications. Capacitors meeting the ER requirements specified herein have a failure rate level (FRL) ranging from 1.0 percent per 1,000 hours to 0.00lpercent per 1,000 hours. These failure rate levels are established at a 90-percent confidence level based on the lifetest parameters specified and are maintained at a 10-percent producer’s risk. An acceleration factor of 8:1 has beenused to relate the life test data at 200 percent of rated voltage at the applicable high test temperature to the ratedvoltage at the applicable high test temperature. A part per million (ppm) quality system is used for documenting andreporting 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 capacitorssupplied to the requirements of this specification.
