The T75 Toroidal PFC Choke is designed for power factor correction (PFC) circuits in high-efficiency AC-DC switching power supplies and industrial power systems. Built with a high-permeability toroidal core and precision winding technology, it provides excellent energy storage capability, low core loss, and stable inductance performance under high current operation.
The toroidal (ring-shaped) structure forms a closed magnetic path, significantly reducing electromagnetic interference (EMI) and improving overall system efficiency. This makes it ideal for high-power, low-noise, and compact power supply designs.
Customized inductance values, wire gauges, and mechanical configurations are available according to different application requirements.
