Abstract

A capacitor includes an anode body, a dielectric layer adjacent to the anode body, a cathode layer adjacent to the dielectric layer, and an enclosure that substantially encloses the anode body, the dielectric layer, and the cathode body. The enclosure has an upper side and an underside and is made of a castable material. The capacitor includes an anode contact having a contact section on the underside of the enclosure, an anode conductor that connects the anode body to the anode contact, and a cathode conductor that contacts the cathode layer and that exits the enclosure. The cathode conductor is a plate having holes at a portion of the cathode conductor inside the enclosure. The holes are at least partially filled with castable material.

Claims (14)

1. A capacitor comprising:

an anode body;

a dielectric layer adjacent to the anode body;

a cathode layer adjacent to the dielectric layer;

an enclosure that substantially encloses the anode body, the dielectric layer, and the cathode layer, the enclosure having an upper side and an underside, the enclosure being comprised of a moldable material;

an anode contact having a contact section on the underside of the enclosure;

an anode conductor that connects the anode body to the anode contact, at least a portion of the anode conductor being inside the enclosure; and

a cathode conductor that contacts the cathode layer and that exits the enclosure, the cathode conductor comprising a plate having holes at a portion of the cathode conductor that is inside the enclosure, the holes being at least partially filled with the moldable material.

2. The capacitor of claim 1 , wherein the cathode conductor bends around an outside surface of the enclosure, a portion of the cathode conductor on the underside of the enclosure forming a contact section.

3. The capacitor of claim 1 , further comprising a material that fixes the cathode conductor to an upper side of the cathode layer adjacent to the upper side of the enclosure.

4. The capacitor of claim 1 , wherein the anode conductor comprises a wire that exits laterally from inside of the anode body.

5. The capacitor of claim 1 , wherein the anode contact and the cathode conductor exit the enclosure at substantially a same height relative to the underside of the enclosure.

6. The capacitor of claim 1 , wherein the underside of the enclosure comprises a mounting surface for fixing the enclosure to a circuit board.

7. The capacitor of claim 1 , wherein the capacitor does not exceed the following dimensions: length=6.0±0.3 mm, width=3.2±0.3 mm, and height=1.5 mm.
