Improved inductive electronic apparatus and methods for manufacturing the same. In one exemplary embodiment, the apparatus comprises an inductive device module comprising N inductors and N+1 core elements. The core elements comprise ferrite core pieces that are optionally identical to one another. These core elements are stacked (e.g., in a longitudinal coaxial arrangement) such that the back of one core element associated with a first inductor provides a magnetic flux path for a second inductor. Form-less (bonded) windings are also optionally used to simplify the manufacture of the device, reduce its cost, and allow it to be made more compact (or alternatively additional functionality to be disposed therein). One variant utilizes a termination header for mating to a PCB or other assembly, while another totally avoids the use of the header by directly mating to the PCB.
