Abstract: A plurality of winding units are each wound in winding channels formed in a bobbin. Each of the winding units include start and finish location conductor portions or termination leads or segments located at predetermined longitudinal and angular positions relative to the longitudinal axis of the bobbin. Longitudinally extensive connecting conductors are located inward of the bobbin outer surface. A plurality of passageways are formed in shoulders or partitions separating the winding channels. These passageways provide access from the outer surface to the connecting conductors. Guide tracks connect the winding channels with the passageways and guide the conductor wire of a winding unit from its winding channel to a passageway for positioning a start or finish conductor portion of the winding unit over the passageway.
