Abstract
A slotted bobbin magnetic component device includes a bobbin having an elongated bobbin tube with transverse slots. One or more substantially flat electrically conductive winding inserts are inserted radially onto the bobbin tube via the transverse slots. At least one detent positioned on the winding insert secures the winding insert on the bobbin and prevents the winding insert from becoming misplaced relative to the bobbin. One or more flanges protruding from the bobbin engage one or more corresponding recesses on the winding insert to prevent angular movement of the winding insert relative to the bobbin. One or more primary conductive winding coils are disposed about the bobbin in the gaps between adjacent winding inserts, the coils being formed by axially winding numerous layers over each other in alternating axial winding directions.
