Product Description
Product Overview
The MSA43-3R0M is a high-performance SMD power inductor designed for low-profile, high-current applications. It features super low resistance and an ultra-high current rating, realized by a metal dust core for high performance (Isat). This inductor is suitable for use in power supplies, battery-powered devices, DC/DC converters, and DC/DC converters for field-programmable gate arrays, operating up to 1MHz. It is ROHS compliant and designed for reliable operation within a wide temperature range.
