Specializing in Toroid and Bobbin Winding


Bobbins are cylinders (with or without flanges) on which wire is wound. The devices function as the container for the wire that acts to create the shape of the coil. Bobbins give ease of assembly for the windings that go in or on the magnetic core.


We work with a variety of different bobbin styles and types. These include, but are not limited to:
  1. Flex leads
  2. Thru-hole pin bobbins
  3. Surface mount bobbins
  4. Air core bonded
