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
L
value.
Weight indicated is per pair or set.
