ETD Cores
Description
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 or an ALvalue.
• AL value is measured at 1 kHz, B < 10 gauss
• Weight indicated is per pair or set.
