Transformer Ferrite Core ETD 54
Ask a questionDescription
These cores are a cross between E cores and Pot cores. Like E cores, they provide a wide opening on each side. This gives adequate space for the large size wires required for low output voltage switched mode power supplies. It also allows a flow of air which keeps the assembly cooler. The center post is round, like that of pot cores. One of the advantages of the round center post is that the winding has a shorter path length around it (11% shorter) than the wire around a square center post with an equal area. This reduces the losses of windings by 11% and enables the core to handle a higher output power. The round center post also eliminates the sharp bend in the wire that occurs with winding on a square center post.
