Abstract
A low cost, low profile and high performance inductive device for use in, e.g., electronic circuits. In one exemplary embodiment, the device includes a four-legged ferrite core optimized for fitting with four or more windings, thereby providing four close-tolerance inductors. Optionally, the device is also self-leaded, thereby simplifying its installation and mating to a parent device (e.g., PCB). In another embodiment, multiple windings per leg are provided. In yet another embodiment, the device has only to opposed legs, thereby reducing footprint. Methods for manufacturing and utilizing the device are also disclosed.
