98 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 ALvalue.
Weight indicated is per pair or set.
