Abstract

Slot core inductors and transformers and methods for manufacturing same including using large scale flex circuitry manufacturing methods and machinery for providing two mating halves of a transformer winding (70). One winding is inserted into the slot of a slot core (110, a, b, c) and one winding is located proximate to the exterior wall of the slot core. These respective halves are joined together using solder pads or the like to form continuos windings through the slot and around the slotted core.
