The pair of end flanges each have an inner face facing one another and an outer face facing away from one another. The inner and outer faces of the pair of end flanges have a plurality of grooves formed in a surface thereof. The grooves provide for enhanced retention of an over-mold that seals a coil within the bobbin assembly.
