KEMET CHT high temperature series

KEMET’s CHT high temperature 260°C surface mount Multilayer Ceramic Capacitors (MLCCs) are constructed of a robust and proprietary C0G/NP0 Base Metal Electrode (BME) dielectric system that offers industry-leading performance at extreme temperatures. These devices are specifically designed for applications in harsh environmental conditions such as down hole oil exploration, industrial high temperature electronics, geothermal, and aerospace which need capacitors that are robust and reliable at extreme temperatures such as 260°C. KEMET’s C0G dielectric exhibits no change in capacitance with respect to time and voltage and boast a negligible change in capacitance with reference to ambient temperature.

KEMET’s CHT high temperature 260°C also incorporates a gold (Au) termination finish providing a clean solderable surface that can withstand the most extreme environments. These devices are Lead (Pb)-Free, RoHS and REACH compliant without the need of any exemptions.
