Product Description
Product Overview
The Unibody Inductor, MSM252012 series, is an integrated power inductor designed for high-current applications. It features a super low resistance and ultra-high current rating, realized by a metal dust core for high performance, particularly in saturation current. This inductor is ROHS compliant and suitable for operating frequencies up to 1MHz. Key applications include low-profile, high-current power supplies, battery-powered devices, DC/DC converters in distributed power systems, and DC/DC converters for field-programmable gate arrays.
