1. An inductive device adapted for use in applications requiring a plurality of inductances, comprising:

  • a magnetically permeable core base element having a plurality of substantially opposed legs each adapted to receive at least one winding thereon, said core base element having;

    a substantially planar first surface;

    at least one vertical riser disposed distally on each of said substantially opposed legs, said at least one vertical riser comprising an interface element comprising a stepped profile, said stepped profile comprising at least two steps; and

    a central riser disposed substantially between said vertical risers;

    a plurality of conductive windings each disposed substantially around said plurality of opposed legs; and

    a magnetically permeable core cap element disposed on at least a top one of said at least two steps and configured to magnetically interface with at least said interface element of said vertical risers wherein said plurality of conductive windings are disposed away from said interface element of said vertical risers.
