MIL-PRF-49467 Specifications and Dimensions

Presidio Components, Inc. is proud to be the first QPL supplier to MIL-PRF-49467, the high voltage ceramic capacitor specification. Per DSCC, this specification covers the general requirements for general purpose, ceramic multilayer high voltage capacitors for use in applications where appreciable variations in capacitance with respect to temperature, voltage, frequency, and life can be tolerated (BR and BZ characteristics) or in critical frequency determining applications, timing circuits, and other applications where absolute stability is required (BP characteristic).

Part or Identifying Number (PIN): Capacitors specified herein are identified by a PIN which consists of the basic number of the performance specification and a coded number. The coded number provides information concerning the characteristic, specification sheet number, capacitance, and capacitance tolerance. The PIN is in the following form with the coded number derived as indicated:
