We specialize in providing custom toroid and bobbin transformers that are built to the exact specs of drawings provided to us. Do not settle for anything less than a perfect fit for your application. We work with a wide variety of materials, cores, and shapes to meet the unique conditions of our customers.

Custom Designs

Do not force your design into a standard package. Work with us to make toroids and bobbins that meet your exact spacing needs. We process small and larger orders (1-500+). Not all our customers know their exact needs, and so we provide solutions in different ways, which include:
  1. Work from electrical/mechanical drawings or specs
  2. Reverse engineer existing parts
  3. Repair parts
  4. Design custom solutions

Specialty Packing

We produce parts that meet all packaging requirements, including MIL-T-27 grades 4,5, and 6. We custom tailor solutions based on our client’s needs. We offer a variety of final assemblies, including potting. Let us help you meet your unique conditions for your applications. We work with:
  1. All terminations/terminals
  2. All wires/pins
  3. All epoxy


Reach out by phone or email to discuss your needs with our team. Once we get specs for your device, we are able to give quotes. We look forward to working with you.
