Abstract
A capacitor that is capable of exhibiting good electrical properties under a wide variety of different conditions is provided. The capacitor contains a capacitor element that includes a sintered porous anode body, a dielectric that overlies the anode body, and a solid electrolyte that overlies the dielectric and includes a conductive polymer. The capacitor also contains multiple exposed anode lead portions that are electrically connected to respective anode terminations and a planar cathode termination that is electrically connected to the solid electrolyte.
Claims23
A solid electrolytic capacitor comprising:
- a capacitor element comprising a sintered anode body, a dielectric that overlies the anode body, and a solid electrolyte that overlies the dielectric, wherein the solid electrolyte includes a conductive polymer, wherein the capacitor element defines opposing first and second ends and opposing upper and lower surfaces;
- a first exposed anode lead portion extending from the first end of the capacitor element;
- a first anode termination that is electrically connected to the first exposed anode lead portion;
- a second exposed anode lead portion extending from the second end of the capacitor element;
- a second anode termination that is spaced apart from the first anode termination and electrically connected to the second exposed anode lead portion;
- and
- a planar cathode termination that is positioned adjacent to the lower surface of the capacitor element and electrically connected to the solid electrolyte.
