Scope.
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 (see 1.2.7). 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 (see 6.7).
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... View More
