ETD Cores (9578444502)

Part Number: 9578444502

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
