KEMET’s industrial-grade, pulse-discharge series, surface-mount capacitors in C0G dielectric deliver the reliable, high-voltage and high-temperature performance required for operation in harsh environments, specifically discharge circuitry. Constructed of a robust and proprietary base metal electrode (BME) dielectric system, these devices offer industry-leading performance relative to capacitance and case size. KEMET's pulse-discharge capacitors average greater than 30% higher breakdown voltage than competitive precious metal electrode (PME) devices with similar capacitance and voltage ratings.

Designed for down-hole oil exploration and perforation, these devices feature a 200°C maximum operating temperature. The electronics industries alliance (EIA) characterizes C0G dielectric as a Class I material. Components of this classification are temperature compensating and are suited for resonant-circuit applications or those where Q and stability of capacitance characteristics are required. Pulse discharge series capacitors in C0G dielectric exhibit no change in capacitance with respect to time and voltage and boast a negligible change in capacitance with reference to ambient temperature. These devices retain high insulation resistance with low dissipation factor at elevated temperatures up to 200°C.

KEMET’s pulse-discharge, surface-mount MLCCs are manufactured in state-of-the-art, ISO/TS, 16949:2009 certified facilities and are proven to function reliably in harsh, high-temperature and high-humidity, down-hole environments.
