AVX military chip ceramic capacitors offer a wide range of
approvals to MIL-PRF-55681. These include standard chip
sizes to english (CDR01-CDR06) and metric (CDR31-CDR35)
units as well as microwave chip capacitor (CDR11-CDR14).
AVX also offers the engineering support necessary for
reliable handling of ceramic chip capacitors. Contact AVX for
additional information on attachment of ceramic chip
capacitors.
