FERROXCUBE  ETD39/20/13-3C90  变压器铁芯, 半芯, ETD, ETD39, 3C90, 92.2 mm, 125 mm²

The from is an ETD ferrite core. It is optimized for use in SMPS transformers with switching frequencies between 50KHz and 200KHz. The designation ETD Economic Transformer Design implies that this design achieves maximum throughput power related to volume and weight of the total transformer. Shielding is improved compared with E cores. The matching coil formers are suitable for many winding type and can be handled on automatic equipment.
