Product Description
Product Overview
The MSA54-4R7M is a high-performance SMD Power Inductor designed for demanding applications. Featuring a metal dust core, it offers super low resistance and ultra-high current ratings with excellent saturation characteristics (I sat). Its compact, low-profile design makes it ideal for space-constrained power supplies, battery-powered devices, and various DC/DC converter applications, including those for distributed power systems and field-programmable gate arrays. This RoHS-compliant inductor operates effectively up to 1MHz.
