Patent number: 8867192Abstract: An electrolytic capacitor is constructed as a stacked structure of alternating anode and cathode plates. A clip is fitted over a peripheral portion of each cathode plate, the clips being welded together to electrically connect the cathode plates in common. The dimensions of the clips are such that the clips take up approximately the same space away from the edges of the cathode plates as the thickness of the anode plate on each side of a cathode plate when the anode and cathode plates are stacked upon one another.Type: GrantFiled: June 30, 2009Date of Patent: October 21, 2014Assignee: Cardiac Pacemakers, Inc.Inventors: Jay E.
