MIL-PRF-123C, PERFORMANCE SPECIFICATION, CAPACITORS, FIXED, CERAMIC DIELECTRIC, (TEMPERATURE STABLE AND GENERAL PURPOSE), HIGH RELIABILITY, GENERAL SPECIFICATION FOR (27 MAR 2003)., This specification covers the general requirements for high reliability, general purpose (BX and BR) and temperature stable (BP and BG) ceramic dielectric fixed capacitors, leaded and nonleaded for space, missile, and other high reliability applications. Capacitors covered by this specification may be used in critical frequency determining applications, timing circuits, and other applications where absolute stability is required (BP and BG), and in applications where appreciable variations in capacitance with respect to temperature, voltage, frequency, and life can be tolerated (BX and BR). Life tests in this specification are performed at two times rated voltage at maximum rated temperature, and an assumed acceleration factor of 8:1 is used to relate life test data obtained at two times rated voltage to performance at rated voltage【英文标准名称】:Ergonomicsofthethermalenvironment-Methodsfortheassessmentofhumanresponsestocontactwithsurfaces-Part1:Hotsurfaces(ISO13732-1:2006);GermanversionENISO13732-1:2006
