MIL-PRF-32663涵盖了主要用于表面安装应用的既定可靠性（ER）和空间级、固定、大块金属箔（BMF）、超精密片式电阻器的一般要求。这些电阻器在正常条件下具有高度的时间稳定性。本规范涵盖的ER电阻器的寿命故障率（FR）为每1000小时1%至0.001%（见1.2.7）。根据寿命试验，这些FRs的置信度为60%。表一总结了这些电阻器的性能特征。设计师在高功率脉冲应用中使用这些电阻器时应注意（见6.7）。

MIL-PRF-32663 covers the general requirements for established reliability (ER), and space level, fixed, bulk metal foil (BMF), ultra-precision chip resistors primarily intended for incorporation into surface mount 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 pulse applications (see 6.7).
