Low inductance electrolytic capacitor

A solid electrolytic capacitor comprising:

• a capacitor element comprising a sintered anode body that includes tantalum, a dielectric that overlies the anode body that includes tantalum pentoxide, a solid electrolyte that overlies the dielectric, and an external coating that overlies the solid electrolyte, wherein the solid electrolyte includes an inner layer that contains an in-situ polymerized conductive polymer and/or an intrinsically conductive polymer and an outer layer containing pre-polymerized conductive polymer particles, and further wherein the external coating includes pre-polymerized conductive polymer particles, 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;
• a housing leaving exposed only a lower surface of the first anode termination, the second anode termination, or both;
• and
• a planar cathode termination that is positioned adjacent to the lower surface of the capacitor element and electrically connected to the solid electrolyte, wherein the housing encloses the capacitor element, leaving exposed only a lower surface of the cathode termination;
• wherein a continuous anode lead extends through the first end and the second end of the capacitor element, thereby defining the first exposed anode lead portion and the second exposed anode lead portion, wherein the exposed lower surface of the planar cathode termination is generally in the same plane as the exposed lower surface of the first anode termination and the second anode termination, and wherein a distance between the first exposed anode lead portion and the second exposed anode lead portion to the lower surface of the capacitor element ranges from about 0.1 millimeters to about 1 millimeter.
