ETD Cores

Fair-Rite ETD Cores have been designed to make optimum use of a given volume of ferrite material for maximum throughput power, specifically for forward converter transformers. The structure, which includes a round center post, approaches a nearly uniform cross-sectional area throughout the core and provides a winding area that minimizes winding losses. ETD Cores can be supplied with the center post gapped to mechanical specifications as well as an A_L value. Fair-Rite ETD Cores are available in a range of sizes from ETD29 to ETD59 and 3 materials with Initial Permeability ranging from 2300 to 3000.
