PERFORMANCE SPECIFICATION
CAPACITORS, VARIABLE, CERAMIC DIELECTRIC,
GENERAL SPECIFICATION FOR
This specification is approved for use by all Department and Agencies
of the Department of Defense.
1. SCOPE
1.1 Scope. This specification covers the general requirements for ceramic dielectric; variable capacitors intended
for operation over a temperature range of -55°C to +85°C, for use in circuits where periodic adjustments are required
(see 6.1).
1.2 Classification.
1.2.1 Type of designation. The type designation is in the following form, and as specified (see 3.1 and 6.2).
CV11
A
070
Style
Characteristic
Capacitance
1.2.1.1 Style. The style is identified by the two-letter symbol "CV" followed by a two-digit number; the letters
identify ceramic dielectric, variable capacitors and the number identifies the shape and dimensions of the capacitor.
1.2.1.2 Characteristic. The characteristic is identified by a single letter in accordance with table I.
1.2.1.3 Capacitance. The nominal maximum rated capacitance value expressed in picofarads (pF) is identified by
a three-digit number; the first two digits represent significant figures and the last digit specified the number of zeros
to follow. When fractional values are required, the letter "R" will be used to indicate the decimal point. For example:
2R5 indicates 2.5 pF.
