High Frequency Componets

At Express Transformers we manufacture a wide range of ferrite based assemblies.

We have machines that can handle ferrite toroids from 8mm OD to 65mm OD. These can be chokes or transformers.

In addition we wind coils to suit the standard range of E and RM cores, as well as custom items based on U and I combination cores for high power applications.
