Product Description
Product Overview
The MS1350-R85M is a unibody power inductor designed for high-current applications. It features super low resistance and an 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 of -55 to +125 and is ROHS compliant.
