Product Overview
The MS0640-3R3M 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 (Isat). This inductor is ROHS compliant and suitable for operating frequencies up to 1MHz. Its low profile makes it ideal for compact power supply designs. Common applications include 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.
