scope:

This specification covers the general requirements for general purpose, ceramic dielectric, insulated, fixed capacitors for use in applications where variations in capacitance with respect to temperature, voltage, frequency, and life can be tolerated.

The type designation shall be in the following form, and as specified (see 3.1 and 6.1 ):

The style is identified by the two-letter symbol "CK" followed by a two-digit number; the letters identify general purpose, ceramic dielectric, fixed capacitors, and the number identifies the shape and dimensions of the capacitor.

The rated temperature and voltage-temperature limits are identified by a two-letter symbol. The first letter indicates the rated temperature as shown in table I; the second letter indicates the voltage-temperature limits as shown in table II. TABLE I. Rated temperature.

Symbol Temperature (range) ------------------------------ °C A - - −55 to +85 B - - −55 to +125 C - - −55 to +150

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" shall be used to indicate the decimal point and the succeeding digits of the group shall represent significant figures. Example: 2R2 indicates 2.2 pf.

The capacitance tolerance is identified by a single letter as shown in table III. TABLE III. Capacitance tolerance.

Symbol Capacitance tolerance -------------------------------------- Percent ± K - - - 10 M - - - 20 --------------------------------------
