MIL-PRF-55182H (AMENDMENT 2),PERFORMANCE SPECIFICATION, RESISTORS, FIXED, FILM, NONESTABLISHED RELIABILITY, ESTABLISHED RELIABILITY, AND SPACE LEVEL, GENERAL SPECIFICATION FOR (22 MAR 2007)., This specification covers the general requirements for nonestablished reliability (non-ER), established reliability (ER), and space level that are hermetically or nonhermetically sealed fixed film resistors that have a high degree of stability with respect to time under severe environmental conditions. ER resistors have failure rates (FR) that are established at 60 percent confidence ranging from 0.001 percent per 1,000 hours to 1.0 percent per 1,000 hours.
