PERFORMANCE SPECIFICATION
CAPACITORS, CHIP, SINGLE LAYER, FIXED, PARALLEL PLATE,
CERAMIC DIELECTRIC, ESTABLISHED RELIABILITY,
GENERAL SPECIFICATION FOR
This specification is approved for use by all Departments
and Agencies of the Department of Defense.
1. SCOPE
1.1 Scope. This specification covers the general requirements for ceramic plate, single layer capacitors. These
capacitors are intended for stripline or microstrip applications, usually at frequencies of 1 GHz and higher. Capacitors
covered by this specification have failure rate levels (FRL) ranging from 1.0 to 0.001 percent per 1,000 hours. These
failure rate levels are established at a 90-percent confidence level and maintained at a 10-percent producer's risk.
They are based on life tests performed at a maximum rated voltage at maximum rated temperature. An acceleration
factor of 8:1 has been used to relate life test data obtained at 200 percent of rated voltage at maximum rated
temperature, to rated voltage at rated temperature. Statistical Process Control (SPC) techniques are required in the
manufacturing process to minimize variation in production of capacitors supplied to the requirements of this
specification.
1.2 Classification. Capacitors covered by this specification are classified by the style, as specified (see 3.1).
1.2.1 Part or Identifying Number (PIN). Capacitors specified herein (see 3.1) are identified by a PIN which
consists of the basic number of the performance specification and a series of coded characters. The coded
characters provide information concerning the capacitors temperature coefficient, specification sheet number,
capacitance value, capacitance tolerance, voltage, case code, termination finish, and failure rate level. The PIN is in
the following form:
