Products in this family are used in the construction of custom magnetic components such as transformers, or for the assembly of such into an end application. In addition to bobbins that provide a surface onto which the desired number of windings for a device can be wound, mounting and assembly hardware such as retaining clips/clamps, insulating washers, adjustment screws, and others are also included. Specifically excluded from this product family are the magnetic core components and wire typically used for the construction of magnetic components; these items are catalogued separately.
