PERFORMANCE SPECIFICATION
CAPACITORS, FEED THROUGH, RADIO-INTERFERENCE REDUCTION,
DC (HERMETICALLY SEALED IN METAL CASES),
ESTABLISHED AND NON-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 established reliability (ER) and non-ER
capacitors designed for operation with direct current (dc), paper, paper plastic, and plastic (extended foil) dielectric,
radio-interference-reduction, feed-through capacitors, hermetically sealed in metal cases (see 6.6.2), for use
primarily in broadband, radio-interference suppression application. Capacitors meeting the established reliability
requirements specified herein have a maximum failure rate of 1%/1000 hours. This failure rate is established with a
90% confidence limit based on the life test parameters specified and are maintained at a 10-percent producer’s risk.
An acceleration factor of 5:1 has been used to relate the life test data obtained at 140 percent of rated dc voltage at
the applicable high test temperature to the rated voltage at the applicable high test temperature.
1.2 Classification.
1.2.1 Part or Identifying Number (PIN). The PIN is in the following form, and as specified (see 3.1 and 6.2):
CZR23 B K B 473 M
