Product Description
T50 High-Current Three-Phase Toroidal Inductor / Common Mode Choke
1. Product Overview
The CHIPSEN T50 Three-Phase Toroidal Inductor is engineered specifically for high-power conversion and grid-tied systems. Built on high-permeability magnetic cores with precision heavy-gauge copper winding and a flame-retardant PCB mounting base, it delivers exceptional common-mode noise attenuation, minimal power loss, and superior phase-to-phase balance. Designed to meet stringent international automotive and industrial standards, the T50 series is the ideal magnetic solution for harsh operating environments where thermal stability and high current handling are paramount.
