Abstract

The invention relates to a printed circuit board comprising capacitive and inductive elements. To arrange such a printed circuit board so that it has a smaller thickness and can be manufactured cost effectively, a printed circuit board is proposed having at least one dielectric layer, on the two side faces of which capacitor electrodes arranged opposite each other are positioned in a first area and two planar windings opposite each other are arranged in at least a second area next to the first area on the side faces of the electric layer.

Claims (18)

1. A printed circuit board, comprising:

a dielectric layer having two side faces;

two capacitor electrodes, each of the two capacitor electrodes disposed on a corresponding one of the two side faces of the dielectric layer, the two capacitor electrodes arranged facing each other in a first area;

two planar windings, each of the two planar windings disposed on a corresponding one of the two side faces of the dielectric later, the two planar windings arranged facing each other in a second area adjacent to the first area; and

two planar magnetic cores, each of the two planar magnetic cores disposed on and spaced apart from a corresponding one of the planar windings.

2. The circuit board of claim 1 , wherein the dielectric layer is positioned between two insulating layers.

3. The circuit board of claim 1 , wherein the planar windings positioned in the second area act both inductively and capacitively.

4. The circuit board of claim 1 , wherein the two planar windings have unidirectional orientations.

5. The circuit board of claim 1 , wherein the two planar windings have winding orientations in opposite directions.

6. The circuit board of claim 1 , wherein a third insulating layer is provided, and wherein on at least one side of the third insulating layer in an area facing the first planar winding, at least a further, third planar winding is provided DC-isolated from the first planar winding.

7. The circuit board of claim 1 , wherein resistive elements are embedded in the printed circuit board.

8. The circuit board of claim 1 , further comprising planar resistive elements, and wherein the two planar magnetic core portions are formed from the same material as each other, and are disposed in a same printed circuit board plane as the planar resistive elements.

9. The circuit board of claim 2 , wherein resistive elements are embedded in the printed circuit board.

10. The circuit board of claim 5 , wherein the planar windings positioned in the second area act both inductively and capacitively.

11. The circuit board of claim 5 , wherein resistive elements are embedded in the printed circuit board.

12. The circuit board of claim 6 , wherein the planar windings positioned in the second area act both inductively and capacitively.

13. The circuit board of claim 6 , wherein resistive elements are embedded in the printed circuit board.

14. The circuit board of claim 4 , wherein the planar windings positioned in the second area act both inductively and capacitively.
