Stable EIA Class II dielectric, with +/-15% temperature
coefficient and predictable variation
of electrical properties with time, temperature and voltage.These chips are designed for sur-
face mount application with nickel barrier terminations suitable for solder wave, vapor
phase or reflow solder board attachment. Also available in silver-palladium terminations for
hybrid use with conductive epoxy. Class II X7R chips are used as decoupling, by-pass, filter-
ing and transient voltage suppression elements.
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
