EI transformers:

Output transformers (SE and PP), single-phase and three-phase power transformers, filter chokes.

 

 

Standard (open) Toroidal transformers:

Output transformers (PP), low profile toroids and power transformers

   

 

Potted and Enclosed Toroidal transformers:

Output and power toroids

   

 

Standard (open) Double-C core transformers:

Output transformers (SE and PP), single-phase and three-phase power transformers, filter chokes

 

 

C core transformers:

Practically one-half of the Double_C transformers, this variety is lower cost and makes great geometry for filter chokes and SE transformers.

 

Potted and Enclosed Double-C core transformers:

Output transformers (SE and PP), single-phase and three-phase power transformers, filter chokes

Integrated power transformer and filter choke in one housing (optional)
