ITG’s 12.4 A power factor chokes feature alloy powder core design

Leigh Electronics has further expanded its range of mid-tier power factor correction chokes (PFCs) providing premium performance at a cost-effective price point. Suitable for applications with continuous conduction requirements in the 100-1,000 Watt range, the company’s PFC222222D Series is designed to meet rigorous AC to DC converter needs for the industrial, equipment, and automotive industries.

An extension of ITG Electronics’ Cubic Design set of power factor correction chokes, PFC222222D Series solutions are viable for Inductance ranges from 260-4500uH and, at a maximum length/width of 21.5 x 22mm and height of 22mm, occupy an exceedingly compact footprint. Compared with traditional toroidal-shaped PFC chokes, the PFC222222DH Series features a flat wire and square core construction to save space and increase power density as much as threefold. The solutions are up to 50% smaller compared with toroidal-shaped PFC chokes with similar power ratings and can reduce DC resistance by as much as 40%, leading to substantially lower copper losses.

ITG Electronics’ PFC222222D Series offers an alloy powder-based DIP Inductor that minimizes core loss, and the chokes’ low-leakage magnetic flux further reduces energy loss and improves overall efficiency. The reasonably priced PFC chokes also come free of any concerns related to thermal aging. The chokes can handle 12.4 Amp with approximately 50% roll-off.
