Switch Mode Transformers

Our switch mode transformers are customized to fit your requirements—we provide a base package (core and bobbin geometry) and you define the rest.

Here's how it works.

1. Pick a series below and choose a base from the series. This will be your base package.
2. Choose a schematic. These can be found at the bottom of any series page.
3. E-mail us and tell us what base package and schematic you have chosen, and other electrical specifications you have. Be as specific as possible.
