Abstract
A method of assembling a coil includes forming a ferrite core having a top end, a bottom end, an inner opening extending from the top end to the bottom end, a cylindrical outer surface, and a step portion formed near the bottom end, the step portion extending past the outer surface. A first high dielectric material is applied on the outer surface of the ferrite core, then a conductive wire is wound onto the high dielectric material, whereafter a second high dielectric material is applied over the conductive wire.
