X7R DIELECTRIC
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 surface
mount application with nickel barrier terminations suitable for sol-
der 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, filtering and transient voltage suppression elements.
