Abstract
Windings for magnetic core devices are preformed as a flat conducting strip disposed in a helical coil configuration of circular shape, having elongated tabs at selectible angles to the coil from substantially tangential to substantially radial orientation for cooperation with the magnetic core exit slots, thereby maximizing core window utilization and adapting to conventional cores. The cross sectional area of the tabs may be substantially less than the cross sectional area of helix turns thereby further eliminating interference with smaller core exit slots. A plurality of such windings are stacked, one on top of the other, or interleaved or placed on torroidal core with flexible orientation of the tabs being available to facilitate access to each of multiple terminals and to isolate or group electrical functions.
