Abstract
A tape wound inductor core device, inductors including same and methods of manufacture. Tape wound material may be cut and/or shaped into 'pucks' that have an exterior surface made up of or defined substantially by the edge surfaces of the layers of the constituent conductive material, with all or most of the broad surfaces disposed inwardly, thereby reducing eddy currents and associated losses. Various puck configurations, inductor arrangements and fabrication techniques are disclosed.
