Product Description
Product Overview
The MS0640-4R7M 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, offering high performance (I sat) and operating up to 1MHz. This inductor is ideal 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 is ROHS compliant.
