ETD Cores (9578394002) Part Number: 9578394002 78 ETD CORE SET 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 are used mainly in switched- mode power supplies and permit off- line designs where IEC and VDE isolation requirements must be met. ETD cores can be supplied with the center post gapped to a mechanical dimension or an A value. L Catalog Drawing 3D Model Weight indicated is per pair or set.
