Product Description
Product Overview
The MS0320-4R7M is a unibody 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. This inductor is suitable for 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. It operates within a wide temperature range and complies with ROHS standards.
