Abstract
Described herein are magnetic core inductors (MCI) and methods for manufacturing magnetic core inductors. A first embodiment of the MCI can be a snake-configuration MCI. The snake-configuration MCI can be formed by creating an opening in a base material, such as copper, and providing a nonconductive magnetic material in the opening. The inductor can be further formed by forming plated through holes into the core material. The conductive elements for the inductor can be formed in the plated through holes. The nonconductive magnetic material surrounds each conductive element and plated through hole. In embodiments, a layered coil inductor can be formed by drilling a laminate to form a cavity through the laminate within the metal rings of the layered coil inductor. The nonconductive magnetic material can be provided in the cavity.
