Large Current Low DCR Inductors (TC1213)

Direct Develops High-Efficiency Coiled Power Inductors with Large Current and Low DCR. Direct has announced a wire-wound power inductor designed for use in the Mother Board of PC and Notebook and various other power devices. The TC1213, measures only 14.0 x 14.5 mm, with a maximum height of 9.5 mm.

Most conventional DC-DC converters use inductors with cores made of relatively expensive metallic materials. By contrast, this product, with a ferrite material, realizes the same DC bias characteristics and other performance features as same-size inductors made with more expensive materials. The TC1213 offers customers much greater design freedom with large current and low DCR by meeting the need to replace power inductors.

Full line products meet RoHS compliant. Direct will also produce devices outside these specifications to meet specific customer requirements, please contact our sales for more information.
