RESISTORS, CHIP, FIXED, FILM, NONESTABLISHED RELIABILITY, ESTABLISHED RELIABILITY, SPACE LEVEL, GENERAL SPECIFICATION FOR
Organization:
ARMY - CR - US Army Communications Electronics Command
Year: 2012
Abstract: This specification covers the general requirements for nonestablished reliability (non-ER), established reliability (ER), and space level, fixed, film, chip resistors primarily intended for incorporation into surface mount and hybrid circuit applications. These resistors have a high degree of stability with respect to time under normal conditions. ER resistors covered by this specification have life failure rates (FR) ranging from 1 percent to 0.001 percent per 1,000 hours. These FRs are established at 60 percent confidence on the basis of life tests. Table I provides a summary of performance characteristics for these resistors. Designers are CAUTIONED on using these resistors in high power pulses applications.Intended Use: The chip resistors covered by this specification are military unique due to the fact that these devices must be able to operate satisfactorily in military systems under the following demanding conditions: 100 cycles of thermal shock at high and low temperature extreme, high temperature for an extended period of time, and low temperature for an extended period of time. In addition, these military requirements are verified under a qualification system and an extended failure rate of 0.001 percent per 1,000 hours. Commercial components are not designed to withstand these military environmental conditions.
