Abstract: A surface mount core assembly (10) comprises a header (20) with breakaway support rails (22). The breakaway support rails are used in the manufacturing process to maximize the core window (16) of the assembly, and may be removed to minimize the footprint of the assembly. In the present embodiment, the assembly comprises, for example, a transformer wherein prefabricated conductor rings are used to further maximize the fill of the core window with conductor material.
