Product Description
Product Overview
The MS1050-2R2M is a unibody power inductor designed for high-current applications. It features a metal dust core for high performance (Isat) and super low resistance with an ultra-high current rating. This inductor is compliant with ROHS standards and operates effectively at frequencies up to 1MHz. It 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.
