This specification covers the general requirements for established reliability, glass dielectric, fixed capacitors. Capacitors covered by this specification have failure rate (FR) levels established in accordance with MIL-STD-690. The reliability for each level is identified by a symbol in accordance with table I. These FR levels are established at a 90 percent confidence level and maintained at a 10 percent producer's risk and are based on life tests performed with rated voltage applied at 125°C. An acceleration factor of 5:1 has been used to relate life test data obtained at 150 percent of rated voltage at 125°C to rated voltage at 125°C. 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 manufacturing process to minimize variation in production of capacitors supplied to the requirements of this specification. TABLE I.
