DC-Link Film Capacitors

KEMET DC-Link Film Capacitors act as an intermediary DC smoothing stage between AC stages. The intermediate DC step allows noise-reduced power transfer when converting between AC sources of different power, frequency, or voltage conditions. DC-link capacitors frequently experience high slew rates that can be detrimental if a suitably robust capacitor is not selected. These capacitors from KEMET are often found in power inverters, high-power charging circuits, and motor drives. Capacitor technologies are sometimes mixed in DC-link applications to target transients and noise that potentially need multiple stages of filtering.
