ETD Cores (9595545402)
Part Number: 9595545402
95 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 ALvalue.

AL value is measured at 1 kHz, B < 10 gauss
A low loss MnZn ferrite material for power applications up to 200 kHz with low temperature variation. New type of 95 material is a low loss power material which features less power loss variation over temperature (25-100°C) at moderate flux densities for operation below 200 kHz.
Available in 95 material:
