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 stability.
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
