本规范涵盖了用于抑制射频/电磁干扰的低通滤波器和电容器的一般要求。按照本规范要求提供的滤波器包含分流电容器和串联电感（FSC 5915）。按照本规范要求提供的电容器包含分流电容器（FSC 5910）。在本规范中，馈通电容器类型（C电路配置）在本文中称为滤波器。 通带功率可以是交流电（ac）和/或直流电（dc），滤波器主要用于减少宽带射频干扰。

This specification covers the general requirements for low-pass filters and capacitors used to suppress radio frequency/electromagnetic interference. Filters furnished to the requirements of this specification contain shunting capacitors and series inductors (FSC 5915). Capacitors furnished to the requirements of this specification contain shunting capacitors (FSC 5910). For the purposes of this specification, feed-thru capacitor types (C circuit configuration) are referred to herein as a filter. Passband power may be alternating current (ac) and/or direct current (dc) and the filter is used primarily in the reduction of broadband radio frequency interference.
