Abstract
Improved form-less electronic apparatus and methods for manufacturing the same. In one exemplary embodiment, the apparatus comprises a shape-core inductive device having a bonded-wire coil which is formed and maintained within the device without resort to a bobbin or other form(er). The absence of the bobbin simplifies the manufacture of the device, reduces its cost, and allows 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. Multi-core variants and methods of manufacturing are also disclosed.

-45. (canceled)
An electronic assembly, comprising:
- at least three core elements mated to one another, the mated core elements collectively forming a plurality of winding channels, each winding channel having a respective aperture associated therewith;
- a plurality of windings, each having a plurality of turns and disposed at least partly within respective ones of the plurality of winding channels, each of the plurality of windings further comprising at least two ends which are routed through their respective aperture;
- and
- a termination element comprising a plurality of electrically conductive terminals associated therewith, the at least two ends of each of the windings being coupled with ones of the terminals.
An electronic assembly useful in a digital subscriber line (DSL) application, comprising:
- a printed circuit board (PCB) having an inductive device mounted thereon, the inductive device comprising:
- a plurality of core elements that are mated to one another, at least a portion of the plurality of core elements comprising a plurality of winding channels, each of the plurality of winding channels having a post foiled from a magnetically permeable material disposed therein;
- wherein the plurality of mated core elements also collectively form a plurality of apertures that communicate with respective ones of the winding channels;
- a plurality of windings, each comprising a plurality of turns and disposed at least partly within one of the winding channels, each winding further comprising at least two ends which are routed through respective ones of the plurality of apertures;
- and
- a termination element comprising a plurality of electrically conductive terminals associated therewith.
An electronic assembly, comprising:
- at least three core elements mated to one another so as to form a plurality of winding channels, each winding channel comprising a respective aperture associated therewith;
- a winding having a plurality of turns and disposed at least partly within at least one of the winding channels;
- and
- a termination element comprising a plurality of electrically conductive terminals associated therewith that protrude from a bottom surface of the termination element, the winding being coupled with at least a portion of the terminals.
