30 ETD CORES ETD29, ETD34, ETD39, ETD44, ETD49, ETD54, ETD59 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. ETD cores can also be supplied to an A L value, these would be supplied in sets. A L value is measured at 1 khz, B < 1 gauss.
