EER Cores (9578282802)

Part Number: 9578282802

78 EER CORE SET

EER cores, similar to ETD cores, have been designed to make optimum use of a given volume of ferrite material for

maximum throughput power. 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.

EER cores can be supplied with the center post gapped to a mechanical dimension or an A
