Abstract
A miniaturized electric coil having a center tap which is constructed from a spiral-like bottom conductor pattern provided on a substrate, an insulating intermediate layer and a spiral-like top conductor pattern which is connected to the bottom conductor pattern via windows in the intermediate layer. A conductor path which is situated in the top conductor pattern is led out from the interior of the top conductor pattern to form the tap. At the area of said conductor path the conductors of the top conductor pattern are locally interrupted but are interconnected by means of said windows and connection conductors in the bottom conductor pattern that are connected parallel to the interruptions so as to ensure an undisturbed current flow in the top conductor pattern.
