Product Description
Product Overview
The MS1335-4R7M-C 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 (I sat). This inductor is suitable for use in 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 frequency range of up to 1MHz and is ROHS compliant.
