The ETD29/16/10-3C90 from Ferroxcube 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.
3C90 core material grade
Inductance factor Al is 2350nH
Relative initial permeability is 1770
Effective magnetic cross section area (Ae) is 76mm2
