Cores type ETD

ETD type cores are mainly used in transformers for impulse power supplies.

Transformers are made on individual orders and according to the requirements of the customers. These are often the development of our designers and implementation departments.

Below are examples of ETD cores and their dimensions that we use for these transformers. The round shape of the center column allows for minimum winding resistance and allows for greater power transfer.
