KEMET Industrial-Grade Pulse Discharge MLCCs
KEMET Industrial-Grade Pulse Discharge MLCCs are surface-mount multilayer ceramic capacitors in C0G dielectric that deliver reliable high-voltage and high-temperature performance required in harsh environments, specifically discharge circuitry. Constructed of a robust and proprietary base metal electrode (BME) dielectric system, these devices offer superior performance relative to capacitance and case size.
KEMET 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.
Available in Sn and SnPb termination options, KEMET’s tin/lead electroplating process is designed to meet a 5% minimum lead content and address concerns for a more robust and reliable lead-containing termination system.
