TRANSFORMERS for
Switch Mode Power Supplies

Most transformers are custom built using standard raw materials. Because standard raw materials are used, their is no additional cost to build custom parts. Below is a sampling of parts available off the shelf. For a custom design, you can fill out our SMPS transformer design worksheet and fax to Rhombus. Or use the worksheet as a guide for the information we need to design a transformer for you. Give us a call or e-mail your specifications.
For new designs take a look at Rhombus standard size ferrite geometries.
