Product Description
Product Overview
The MS0320-3R3M is a unibody power inductor designed for high-performance applications. It features super low resistance and an ultra-high current rating, achieved through a metal dust core, enabling high saturation current. This inductor is suitable for low-profile, high-current power supplies, battery-powered devices, and various DC/DC converters, including those in distributed power systems and for field-programmable gate arrays. It operates effectively up to 1MHz and is ROHS compliant.
