KEMET Power Solutions KPS Series MLCC Capacitors

Kemet Power Solutions - KPS SeriesThe KEMET Power Solutions (KPS) MLCC Capacitors deliver double the capacitance in the same or smaller footprint than traditional SMT MLCC devices. The surface mountable KPS series features lead-frame technology to vertically stack single or dual MLCC ceramic chips into a parallel circuit and single compact SMT package. The attached lead-frame mechanically isolates the capacitor/s from the printed circuit board, thereby offering advanced mechanical and thermal stress protection well beyond traditional multilayer ceramic surface mount capacitors. Isolation also addresses concerns for audible, microphonic noise that may occur when a bias voltage is applied.

The KPS Series is ideal for applications with piezoelectric or mechanical noise concerns such as in the industrial, automotive, military, and telecom industries. The KEMET KPS MLCC Capacitors are also useful in smoothing circuits, DC-to-DC converters, power supplies, and to increase flex resistance in board flex applications (up to 10mm). The AEC-Q200 Automotive Qualified KPS Series MLCC capacitors are also available.

Available in X7R dielectric, KEMET's KPS is a lead-free, RoHS compliant, non-polar device. By utilizing ceramic technology, KPS offers significant advantages in ESR and ESL when compared to other dielectric solutions.
