ARMY MIL-PRF-49470 B-2003 CAPACITOR, FIXED, CERAMIC DIELECTRIC, SWITCH MODE POWER SUPPLY (GENERAL PURPOSE AND TEMPERATURE STABLE), STANDARD RELIABILITY AND HIGH RELIABILITY, GENERAL SPECIFICATION FOR
This specification covers the general requirements for general purpose(BQ, BR, and BX characteristics) and temperature stable(BP characteristic) ceramic capacitors for use in switch mode power supplies. Two product levels are offered: B level(standard reliability) and T level(high reliability). 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.
