One world. One KEMET

Overview

KEMET Power Solutions (KPS) Commercial Series stacked

capacitors 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, therefore offering

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 when compared to

traditional surface mount MLCCs 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.

Combined with the stability of an X7R dielectric, KEMET’s

KPS Series devices exhibit a predictable change in

capacitance with respect to time and voltage and boast a

minimal change in capacitance with reference to ambient

temperature. Capacitance change is limited to ±15% from

−55°C to +125°C.
