KPS Series Capacitors

KEMET adds tin-lead option to their KPS series capacitors

KEMET Power Solutions' KPS (KEMET power solutions) series utilizes proprietary lead frame technology to vertically stack one or two MLCCs into a parallel circuit in a single, compact surface mount package. The lead frame isolates the capacitors from the printed circuit board, offering advanced mechanical and thermal stress performance and addressing concerns for audible, microphonic noise that may occur when a bias voltage is applied.

Stacking allows for up to double the capacitance in the same or smaller design footprint when compared to traditional surface mount MLCC devices. A two-chip stack offers up to double the capacitance in the same or smaller design footprint when compared to traditional surface mount MLCC devices.

Providing up to 10 mm of board flex capability, KPS series capacitors are environmentally friendly and in compliance with RoHS legislation. Available in X7R dielectric, these devices are capable of Pb-free reflow profiles and provide lower ESR, ESL, and higher ripple current capability when compared to other dielectric solutions.
