MIL-PRF-39001D, PERFORMANCE SPECIFICATION, CAPACITORS, FIXED, MICA DIELECTRIC, ESTABLISHED RELIABILITY AND NONESTABLISHED RELIABILITY, GENERAL SPECIFICATION FOR (2 MAR 2004)., This specification covers the general requirements for established reliability (ER) and nonestablished reliability (non-ER), mica dielectric, fixed capacitors (see 6.1). The ER capacitors have a failure rate level (FRL) ranging from 1.0 percent per 1,000 hours to 0.001 percent per 1,000 hours (see 1.2.1.7). The FRL is established at a 90 percent confidence level. The FRL, identified by the applicable symbol specified in table V is referred to operational life at full rated voltage (see 1.2.1.6) at 125?C or 150?C, as applicable. An acceleration factor of 25:1 has been used to relate the life test at 150 percent of rated voltage at rated temperature to rated voltage at rated temperature.”【英文标准名称】:Aluminiumalloys,castingalloys;sandcasting,gravitydiecasting,pressurediecasting,investmentcasting
