MIL-PRF-914C, PERFORMANCE SPECIFICATION, RESISTOR NETWORKS, FIXED, FILM, SURFACE MOUNT, NON-ESTABLISHED RELIABILITY, AND ESTABLISHED RELIABILITY, GENERAL SPECIFICATION FOR (22 APR 2008) [SUPERSEDING MIL-R-914]., This specification covers the general requirements for non-established reliability (non-ER) and established reliability (ER), hermetically sealed (see 3.27) and nonhermetically sealed networks (see 3.27.1). These networks consist entirely of fixed, film resistors. They are primarily intended for use in surface mount applications where space is a major concern. ER resistors covered by this specification will have life failure rates (FR) ranging from 1 percent to 0.001 percent per 1,000 hours (see 1.2.1.7). The ER FR are established at a minimum 60-percent confidence level on the basis of life tests.【英文标准名称】:Metalhalidelamps;Amendment1
