KEMET’s Industrial Grade Pulse Discharge Series surface mount capacitors in C0G Dielectric, available from Farnell element14, deliver reliable high voltage and high temperature performance required for operation in harsh environments, specifically discharge circuitry. Constructed of a robust and proprietary BME dielectric system, these devices offer industry-leading performance relative to capacitance and case size. The capacitors average greater than 30% higher breakdown voltage than competitive PME devices with similar capacitance and voltage ratings. Designed for down-hole oil exploration and perforation, these devices feature a 200C maximum operating temperature. The 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 200C. Their 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.
