CET Planar Transformer

At CET Technology, we manufacture custom Planar transformers. They can be ordered through our RFQ form.

What Are Planar Transformers?

Planar transformers are transformers with winding coils that are in a predominantly spiral configuration, most often as traces on a PCB. This allows the transformer to be lower profile than traditionally wound transformers, and maintain high power densities.

Planar is most suited for very high switching frequency applications, and they are often used in military and aerospace projects. Because of the PCBs used, there may be initial tooling charges. CET Technology can design and manufacture new planar transformers for your application, or customize existing designs.

Planar is a great option as more industries are now pushing toward higher efficiency and performance along with miniaturization of transformers. It is a great alternative to wire-wound transformers.
