1. A method of manufacturing an inductive device, comprising:
obtaining a core comprising an axial portion, a first flange portion and a second flange portion, with the first flange portion being disposed on an opposing side of the axial portion with the second flange portion, the first flange portion comprising a first plurality of interface connections and the second flange portion comprising a second plurality of interface connections;
securing a first of a pair of primary windings to the first flange portion;
securing a first of a pair of secondary windings to the first flange portion;
winding the first of the pair of primary and secondary windings about the axial portion of the core in a first direction;
securing the first of the pair of primary windings to the second flange portion;
securing the first of the pair of secondary windings to the second flange portion;
securing a second of the pair of primary windings to the second flange portion;
securing a second of the pair of secondary windings to the second flange portion; and
subsequent to the winding of the first of the pair of primary and secondary windings in the first direction, winding the second of the pair of primary and secondary windings about the axial portion of the core in a second direction opposite to the first direction, so as to complete a complete set of windings within two traversals across the axial portion of the core, the said complete set of windings is composed of the first of the pair of primary and secondary windings and the second of the pair of primary and secondary windings.
