KEMET L Series MLCCs use a unique lead-frame technology, with tin/lead termination stacked capacitors vertically stacking one or two multilayer ceramic chip capacitors into a single, small surface mount package. The lead frame that is attached provides superior mechanical and thermal stress performance by mechanically separating the capacitors from the printed circuit board. Typical applications of L series MLCCs include military, aerospace, and industrial.
KEMET KPS L Series MLCCs
Overview
Isolation addresses concerns about audible, microphonic noise that could arise from applying a bias voltage. KEMET's tin/lead electroplating process addresses the need for a more durable and dependable lead-containing termination solution with a 5% minimum lead content and up to 10mm of board flex flexibility. L series MLCCs are RoHS compliant. These devices offer lower ESR, ESL, and higher capability for ripple current. Devices from KEMET's L series MLCCs show a minimum change in capacitance for ambient temperature and a predictable change in capacitance with respect to time and voltage when combined with the stability of an X7R dielectric.
