Unibody Power Inductor
Product Overview
The MS0840-100M 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, including a high saturation current (I sat). This inductor is suitable for a wide frequency range up to 1MHz and is ROHS compliant. Its compact, low-profile design makes it ideal for space-constrained applications such as 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 (FPGAs).
