Surface Mount Multilayer Ceramic Chip Capacitors
KPS Series – Commercial Grade (X7R Dielectric)
Overview
KEMET’s
KPS
Series (KEMET
Power Solutions)
utilizes
proprietary lead-frame technology to vertically stack one or two
multilayer ceramic chip capacitors (MLCCs) 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 MLCC devices.
Providing up to 10mm 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.
