KEMET’s COG dielectric surface mount multilayer ceramic chip capacitors (SMD MLCCs) offer a 125°C maximum operating temperature and are considered “stable” with no change in capacitance with respect to time and voltage.

These capacitors feature a wide operating temperature range of -55°C to +125°C, are lead (Pb)-free, RoHS, and REACH compliant, and come in various case sizes (EIA 0201, 0402, 0603, 0805, 1206, 1210, 1808, 1812, 1825, 2220, and 2225) with DC voltage ratings from 10 V to 250 V.

They offer capacitance values ranging from 0.5 pF to 0.47 μF, with available capacitance tolerances of ±0.10 pF, ±0.25 pF, ±0.5 pF, ±1%, ±2%, ±5%, and ±10%.

Key Benefits

No piezoelectric noise, extremely low ESR and ESL, high thermal stability, and high ripple current capability.


Typical applications include critical timing, tuning, circuits requiring low loss, circuits with pulse, high current, decoupling, bypass, filtering, transient voltage suppression, blocking, and energy storage.
