Abstract:
A low cost, high performance inductive device for use in, e.g. electronic circuits is disclosed. In one exemplary embodiment, the device includes a two-legged magnetically permeable core optimized for fitting with one or more windings. Preferably, the device is also self-leaded, thereby simplifying its installation and mating to a parent device (e.g., PCB). In another embodiment, one or more low profile magnetically permeable cores are mounted on a surface of the self-leaded magnetically permeable core, preferably with a gap. In yet another embodiment, the aforementioned gap is obviated. In yet another embodiment, spacers are positioned on a surface of the self-leaded magnetically permeable core device to position the low profile magnetically permeable at a predetermined distance from the self-leaded magnetically permeable core. In yet another embodiment, a bead inductor is disclosed comprising a plurality of turns. Methods for manufacturing and utilizing the devices are also disclosed.
