Patent ID: 11222754

Abstract:
A solid electrolytic capacitor and method for making the capacitor are provided. The capacitor includes a sintered porous anode body formed from a valve metal, a metallic physical vapor deposition (PVD) layer disposed directly on a planar surface of the anode body, a dielectric, a cathode, and anode and cathode terminations. The dielectric overlies at least a portion of the anode body and is also formed within the anode body. The cathode overlies at least a portion of the dielectric that overlies the anode body and includes a solid electrolyte, and a portion of a lower surface of the metallic PVD layer is free of both the dielectric and solid electrolyte. The anode termination is electrically connected to the portion of the lower surface of the metallic PVD layer that is free of both the dielectric and solid electrolyte, and the cathode termination is electrically connected to the solid electrolyte.
