Large-Current Power Inductors - TPI Series

KEMET ferrite core inductors are designed for a very low core loss

Image of KEMET's TPI Series Large Current Power InductorsThe core material used in KEMET TPI ferrite core inductor is ideal for high switching frequency applications. The inductor's flat-wire one-turn-through-the-construction design enables high efficiency at large currents. It also has a high switching frequency, low core loss, high current, and low self-heating with an operating temperature up to +125°C. Typical applications include high-switching DC/DC power supplies, points of load (POL), servers and storage, and supercomputers.

The TPI series offers two solutions. One set of parts are DC-optimized inductors for hard SW topology, 12 V power distribution, DC/DC power supplies, POL, servers and storage, and supercomputers. The other set comprises AC-optimized inductors for soft SW topology, 48 V power distribution. The AC optimized inductors were developed for switched tank convertor (STC) technology, which reduces close to 50% of the total loss compared to conventional inductors
