Transformers EFD

Transformers and coils with an EFD ferrite core ("Economic Flat Design") offer considerable benefits in the miniaturization of circuits. The power density of the ferrite core is proportional to the volume, thus having a significant influence on the size of power supplies and converters. The low profile and high power density of this type of core make transformers ideal for applications where minimal dimensions are intended. The EFD-series is also suitable for frequencies of > 1MHz
