本规范涵盖了已建立的可靠性（ER）和非ER电容器的一般要求，这些电容器设计用于直流（dc）、纸、纸塑和塑料（扩展箔）电介质、无线电干扰减少、馈通电容器、密封在金属外壳中（见6.6.2），主要用于宽带无线电干扰抑制应用。满足本文规定的既定可靠性要求的电容器的最大故障率为每1000小时1.0%。该故障率由90- 基于指定的寿命测试参数的置信限百分比，并保持在10%的生产商风险下。使用5:1的加速系数将在适用的高试验温度下140%额定直流电压下获得的寿命试验数据与适用的高测试温度下的额定电压联系起来。

This specification covers the general requirements for established reliability (ER) and non-ER capacitors designed for operation with direct current (dc), paper, paper plastic, and plastic (extended foil) dielectric, radio-interference-reduction, feed-through capacitors, hermetically sealed in metal cases (see 6.6.2), for use primarily in broadband, radio-interference suppression application. Capacitors meeting the established reliability requirements specified herein have a maximum failure rate of 1.0 percent per 1,000 hours. This failure rate is established with a 90-percent confidence limit based on the life test parameters specified and are maintained at a 10-percent producer‰Ûªs risk. An acceleration factor of 5:1 has been used to relate the life test data obtained at 140 percent of rated dc voltage at the applicable high test temperature to the rated voltage at the applicable high test temperature.
