MIL-PRF-39014G, PERFORMANCE SPECIFICATION, CAPACITOR, FIXED, CERAMIC DIELECTRIC (GENERAL PURPOSE), ESTABLISHED RELIABILITY AND NON-ESTABLISHED RELIABILITY, GENERAL SPECIFICATION FOR (16 JUN 2005)., This specification covers the general requirements for established reliability (ER) and nonestablished reliability (non-ER), (product level C), general purpose, ceramic dielectric, insulated, fixed capacitors for use in applications where appreciable variations in capacitance with respect to temperature, voltage, frequency, and life can be tolerated (see 6.1). ER capacitors covered by this specification have failure rate levels (FRL) (M, P, R, and S) ranging from 1.0 percent to 0.001 percent per 1,000 hours. 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 at maximum rated temperature. An acceleration factor of 8:1 has been used to relate life test data obtained at 200 percent of rated voltage at maximum rated temperature, to rated voltage at rated temperature.
