Abstract

A capacitor component is disclosed. In an embodiment a capacitor component includes a winding having an oval core hole, which has a maximum diameter and a minimum diameter, wherein the minimum diameter is smaller than the maximum diameter, and wherein the winding is designed such that a deformation of the winding that occurs only locally is producible by a force acting punctiformly on the winding.

Claims (16)

1. A capacitor component comprising:

a winding comprising an oval core hole, which has a maximum diameter and a minimum diameter,

wherein the minimum diameter is smaller than the maximum diameter,

wherein the winding has an inner winding region that is free of electrodes,

wherein the inner winding region adjoins the oval core hole in a radial direction toward the outside and has a diameter of at least 35% of a diameter of the winding, and

wherein the inner winding region consists essentially of paper and an electrolyte.

2. The capacitor component according to claim 1 , wherein the inner winding region has a diameter of at least 45% of the diameter of the winding.

3. The capacitor component according to claim 1 , wherein the maximum diameter of the core hole is at least 6 mm and/or at least 25% of the diameter of the winding.

4. The capacitor component according to claim 1 , wherein the maximum diameter of the core hole is at least 35% of a diameter of the winding.

5. The capacitor component according to claim 1 , wherein the winding has a diameter in a range of from 7 mm to 30 mm.

6. The capacitor component according to claim 1 , wherein the winding has a diameter in a range of from 10 mm to 22 mm.

7. The capacitor component according to claim 1 , wherein the maximum diameter of the core hole is at least one millimeter greater than the minimum diameter.

8. The capacitor component according to claim 1 , wherein the capacitor component has an anode terminal and a cathode terminal, wherein each anode terminal and cathode terminal are contact-connected to the winding and are arranged on mutually opposite sides of the core hole.

9. The capacitor component according to claim 8 , wherein a connecting line between the anode terminal and the cathode terminal is perpendicular to the maximum diameter of the winding.

10. The capacitor component according to claim 1 , wherein the capacitor component is an electrolytic capacitor.

11. The capacitor component according to claim 1 , further comprising a housing, wherein a bead is formed in the housing, wherein the winding is arranged in the housing and wherein the winding is held in the housing by the bead.
