PFC28282xB Series Power Factor Correction Chokes
ITG Electronics’ wirewound alloy powder PFC chokes feature a square core that saves board space and improves the power density
ITG Electronics’ PFC282820B, PFC282822B, and PFC282829B series power factor correction (PFC) chokes provide a slim footprint for engineers to save space on all PFC designs. All three series are capable of 500 W to 1000 W continuous conduction mode PFC boost converter applications. The PFC282829B series, with a wider design (27.5 mm x 28.5 mm), is compatible with power systems up to 2,000 watts.
The PFC28282xB series chokes differ slightly from the traditional toroidal-shaped PFC chokes. Their innovative design features a square core with a flat wire wrapped in the middle of the square core. Using this square core saves board space and improves the power density.
These chokes are tailored specifically to facilitate efficient AC-to-DC power conversion within the demanding operational environments of industrial equipment and automotive component manufacturing sectors. Engineered with precision and adherence to industry standards, these PFC chokes exhibit a remarkable blend of robust performance and space-efficient design, effectively addressing the unique needs of high-volume production settings inherent to these industries.
PFC28282xB series chokes with meticulously crafted attributes ensure optimal power conversion efficiency and contribute significantly to streamlining assembly processes, enhancing overall productivity and cost-effectiveness. With a keen focus on reliability and performance, these chokes provide innovative solutions that empower manufacturers to meet the rigorous demands of their respective sectors while maintaining a competitive edge in today’s dynamic marketplace.
