KEMET Power Solutions' KPS-MCC series high temperature SMPS ceramic stacked capacitors combine a robust and proprietary C0G/NPO base metal electrode (BME) dielectric system for high temperature and high power SMPS applications. These devices are specifically designed to withstand the demands of harsh industrial environments such as down-hole oil exploration and automotive/avionics engine compartment circuitry.

The KPS-MCC is constructed using large chip multilayer ceramic capacitors (MLCCs), horizontally stacked and secured to a lead-frame termination system using a high melting point (HMP) solder alloy. The lead-frame isolates the MLCCs from the printed circuit board (PCB) while establishing a parallel circuit configuration. Mechanically isolating the capacitors from the PCB improves mechanical and thermal stress performance, while the parallel circuit configuration allows for bulk capacitance in the same or smaller design footprint.

KEMET’s high temperature C0G capacitors are temperature-compensating and are well suited for resonant circuit applications, or for those where Q and stability of capacitance characteristics are required. They exhibit no change in capacitance with respect to time and voltage, and boast a negligible change in capacitance with reference to ambient temperature. Capacitance change is limited to ±30 ppm/°C from -55°C to +200°C. In addition, these capacitors exhibit high insulation resistance with low dissipation factor at elevated temperatures up to +200°C. They also exhibit low ESR at high frequencies and offer greater volumetric efficiency over competitive high temperature BME ceramic capacitor devices.
