MIL-PRF-39007J (AMENDMENT 1), PERFORMANCE SPECIFICATION: RESISTORS, FIXED, WIRE WOUND (POWER TYPE), NONESTABLISHED RELIABILITY, ESTABLISHED RELIABILITY, AND SPACE LEVEL, GENERAL SPECIFICATION FOR (17 OCT 2008)., This specification covers the general requirements for nonestablished reliability (non-ER), established reliability (ER), or space level, axial lead precision, power type, wire wound, fixed resistors having a +25?C ambient operating temperature derated to zero load at +250?C for use in electrical, electronic communication, and associated equipment. These resistors have initial resistance tolerances of ?.5 percent, ?.1 percent, and ?1 percent, and a resistance temperature characteristic as given in table I. ER resistors covered by this specification will have failure rates (FR) ranging from 1 percent to .001 percent per 1,000 hours (see 1.2.1.5). These FR are established at 60 percent confidence on the basis of life tests (permissible resistance change of 1.0 percent). Resistors which are noninductively wound with solderable terminals are designated by a terminal designated "N" and "Z". Terminals designated by the letters "S" and "W" are inductively wound with solderable and weldable terminals (see 1.2.1.2).
