PFC433835B Series - High-Frequency Power Factor Correction Chokes

ITG Electronics PFC433835B series high-power PFC inductors are optimized for compact, high-efficiency applications

Image of ITG Electronics PFC433835B Series - High-Frequency Power Factor Correction Chokes ITG Electronics PFC433835B series are a high-frequency power factor correction (PFC) choke lines designed for next-generation CCM boost converter topologies. These PFC chokes are ideal for AC-DC conversion applications requiring switching frequencies between 100 kHz to 200 kHz, with power ratings up to 3,300 W and support for output currents up to 50 A.

As part of the ITG Cubic Design Inductor family, the PFC433835B series incorporates square core architecture and flat wire windings, an engineering choice that delivers up to 50% reduction in size and 40% lower DC resistance compared to conventional toroidal PFC chokes. These attributes result in higher power density, reduced copper loss, and superior thermal performance, enabling efficient system designs in constrained spaces.
