MIL-PRF-55681E, PERFORMANCE SPECIFICATION: CAPACITOR, CHIP, MULTIPLE LAYER, FIXED, CERAMIC DIELECTRIC, ESTABLISHED RELIABILITY AND NON-ESTABLISHED RELIABILITY, GENERAL SPECIFICATION FOR (03-JUL-1997) [SUPERSEDING MIL-C-55681D]
MIL-PRF-55681E, PERFORMANCE SPECIFICATION: CAPACITOR, CHIP, MULTIPLE LAYER, FIXED, CERAMIC DIELECTRIC, ESTABLISHED RELIABILITY AND NON-ESTABLISHED RELIABILITY, GENERAL SPECIFICATION FOR (03-JUL-1997) [SUPERSEDING MIL-C-55681D]., This specification covers the general requirements for non-established reliability (non-ER) and
established reliability (ER), ceramic dielectric, multiple layer, chip capacitors. ER capacitors covered by this
specification have failure rate levels (FRL) 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.
