Ferroxcube Ferrite Etd Cores Transformer Core

The ETD core design is a further
development of
E cores. They are optimized for use
in SMPS transformers with switching
frequencies between 50 and 200
kHz. 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
somewhat improved compared with
E cores. The matching coil formers
are suitable for many winding types
and can be handled on automatic
equipment.
