1. An apparatus comprising:
a bobbin comprising:
a shell configured to at least partially surround a leg of a magnetic core and to support a primary winding and a secondary winding to each be disposed around an outer surface of the shell; and
a first flange comprising a region of partial conductivity on a surface of the first flange, wherein in cross section the region of partial conductivity extends diagonally away from the magnetic core,
wherein the first flange is shaped to follow a circumference of the shell and to at least partially surround the leg of the magnetic core, and
wherein the region of partial conductivity comprises:
a concave surface facing toward the leg of the magnetic core; and
a convex surface that is opposite the concave surface and that faces away from the leg of the magnetic core.
