Abstract
An electrolytic capacitor including-includes an anode body that is porous, an anode wire including a buried part buried in the anode body and a protrusion part protruding to an outside of the anode body, a dielectric layer disposed on a surface of the anode body, a cathode part covering at least a part of the dielectric layer, an anode terminal electrically connected to the anode wire, and a cathode terminal electrically connected to the cathode part. A corner defined by three sides of the anode body is chamfered by an intersecting surface intersecting each of the three sides, the three sides intersecting each other. The protrusion part is protruded from the intersecting surface and is connected to the anode terminal.
Claims6
An electrolytic capacitor comprising:
- an anode body that is porous;
- an anode wire including a buried part buried in the anode body and a protrusion part protruding to an outside of the anode body;
- a dielectric layer disposed on a surface of the anode body;
- a cathode part covering at least a part of the dielectric layer;
- an anode terminal electrically connected to the anode wire;
- a cathode terminal electrically connected to the cathode part;
- and
- an outer package covering the anode body, wherein:
- a corner defined by three sides of the anode body is chamfered by an intersecting surface intersecting each of the three sides, the three sides intersecting each other,
- the protrusion part is protruded from the intersecting surface and is connected to the anode terminal,
- two intersecting surfaces are disposed at respective both ends of one of the three sides, the two intersecting surfaces including the intersecting surface,
- the outer package includes a bottom surface and an upper surface opposite to the bottom surface,
- the anode terminal includes a bottom-side terminal part and two anchor parts, the bottom-side terminal part being exposed from the outer package at the bottom surface, the two anchor parts each extending from the bottom-side terminal part and buried in the outer package, and
- each of the two anchor parts extends toward a corresponding one of the two intersecting surfaces, and the protrusion part is connected to a corresponding one of the two anchor parts.
