This specification covers the requirements for high reliability, discoidal, ceramic dielectric, fixed capacitors. This specification provides for two levels of product requirements: Class B and class S. Capacitors furnished to the requirements of this specification are intended for use in Radio Frequency/ Electromagnetic Interference (RFI/EMI) suppression filters covered by MIL-PRF-28861. This specification establishes a Qualified Manufacturers List (QML) for discoidal capacitors that requires demonstration of control of the quality system and manufacturing process and qualification of representative discoidal capacitor designs.
