Commercial & Automotive KPS High-Voltage MLCCs KEMET Commercial and Automotive High-Voltage MLCCs utilize a proprietary lead-frame technology to vertically stack one or two multilayer ceramic chip capacitors into a single compact surface-mount package. The attached lead frame mechanically isolates the capacitor(s) from the printed circuit board (PCB), providing advanced mechanical and thermal stress performance. Isolation also addresses concerns for audible microphonic noise that may occur when a bias voltage is applied. A two-chip stack offers up to double the capacitance in the same or smaller design footprint compared to traditional surface-mount MLCC devices.
