GENERAL SPECIFICATION FOR
This specification is approved for use by all Departments
and Agencies of the Department of Defense.
INACTIVE FOR NEW DESIGN
AFTER 24 AUG 79, USE MIL-PRF-23269
1. SCOPE
1.1 Scope. This specification covers the general requirements for glass-dielectric, fixed capacitors enclosed in
glass, epoxy or porcelain cases, suitably protected against high humidity.
1.2 Classification.

1.2.1.1 Style. The style is identified by the two-letter symbol "CY" followed by a two-digit number; the letters
identify glass and porcelain dielectric, fixed capacitors, and the number identifies the shape and dimensions of the
capacitor.
1.2.1.2 Operating temperature range. The operating temperature range is identified by a single letter in
accordance with table I.
TABLE I. Operating temperature range.
Operating temperature range, °C
Symbol
C
-55 to +125
1.2.1.3 Capacitance. The nominal capacitance value, expressed in picofarads (pF), is identified by a three-digit
number; the first two digits represent significant figures and the last digit specifies the number of zeros to follow.
When fractional values of a pF are required, the letter "R" is used to indicate the decimal point and the succeeding
digits of the group represent significant figures. Example: 1R5 indicates 1.5 pF.
