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. Their 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.
• Part number is for a single core.
• ETD cores can be supplied with the center post gapped to a mechanical dimension.
• ETD cores can also be gapped to an A
• A
• See section “The Effect of Direct Current on the Inductance of a Ferrite Core” on page 165 for curves of A
• The ETD cores are in conformance with IEC 61185.
• For any ETD core requirement not listed in the catalog, please contact our customer service group for
