Abstract
An inductive device comprises a plate-shaped ferrite core and a hybrid double-D solenoid coil which is arranged over the plate-shaped ferrite core and has a plurality of turns. The plurality of turns is grouped into at least two groups, each having at least two immediately consecutive turns which in a group have monotonically increasing or decreasing turn diameters, wherein the last turn of a group has a turn diameter that is larger than that of the first turn of the following group if the turn diameter of the turn immediately preceding the last turn within the group is smaller than the turn diameter of the last turn, or has a turn diameter that is smaller than that of the first turn of the following group if the turn diameter of the turn immediately preceding the last turn is larger than the turn diameter of the last turn.
