COG DIELECTRIC
Ultra stable Class I dielectric (EIA COG) or NPO:
linear temperature coefficient, low loss, stable electrical
properties with time, voltage and frequency. Designed for
surface mount application with nickel barrier termination
suitable for solder wave, vapor phase or reflow solder board attachment. Also
available with silver-palladium terminations for hybrid use with conductive
epoxy. COG chips are used in precision circuitry requiring Class I sta-
bility.
CAPACITANCE & VOLTAGE SELECTION FOR POPULAR CHIP SIZES
3 digit code: two significant digits, followed by number of zeros eg: 183 = 18,000 pF. R denotes decimal, eg. 2R7 = 2.7 pF
