Product Description
Product Overview
The MSM252012 series is a range of unibody power inductors designed for high-current applications. These inductors feature a super low resistance and ultra-high current rating, realized by a metal dust core for high performance. They are compliant with ROHS standards and are suitable for operating frequencies up to 1MHz. Typical 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.
