Product Description
Product Overview
The MQ1050-R68M 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 low-profile, high-current power supplies, battery-powered devices, and DC/DC converters in distributed power systems and for field-programmable gate arrays. It operates within a frequency range of up to 1MHz and complies with ROHS standards.
