    摘要: Generally, methods and processes for assembling magnetic components are presented herein. More specifically, conductors are wound around a substantially hollow bobbin. Portions of the conductors may be temporarily positioned outside the bobbin through slots in the flanges of the bobbin during the assembly process. Insulating layers may be wrapped around the conductors. The center legs of a pair of magnetic core halves may be inserted into the bobbin. The base of the magnetic core halves may have a passage to allow a conductor to pass therethrough at a height less than the height of the base.
