摘要： An integrated capacitor assembly that contains at least two solid electrolytic capacitor elements electrically connected to common anode and cathode terminations is provided. The capacitor elements contain an anode, a dielectric coating overlying the anode that is formed by anodic oxidation, and a conductive polymer solid electrolyte overlying the dielectric layer. The capacitor elements are spaced apart from each other a certain distance such that a resinous material can fill the space between the elements. In this manner, the present inventors believe that the resinous material can limit the expansion of the conductive polymer layer to such an extent that it does not substantially delaminate from the capacitor element. In addition to possessing mechanical stability, the capacitor assembly also possesses a combination of good electrical properties, such as low ESR, high capacitance, and a high dielectric breakdown voltage.

摘要： A solid electrolytic capacitor capable of exhibiting stable electrical properties is provided. The capacitor contains an oxidized anode and a conductive polymer coating overlying the anode. The conductive polymer coating contains multiple layers formed from a dispersion of pre-polymerized conductive polymer particles. The present inventors have surprisingly discovered that capacitors formed from such conductive polymer dispersions can operate at high voltages and achieve good electrical performance at relatively high humidity and/or temperature levels and that the problem of layer delamination may be overcome by carefully controlling the conductive polymer coating configuration and the manner in which it is formed. Namely, the coating contains a first layer hat only partially covers the anode so that the gaseous bubbles generated within the first layer can escape via the uncoated portion without tearing away portions of the polymer layer, minimizing formation of surface inhomogeneities that could lead to delamination.

摘要： A solid electrolytic capacitor that is capable of exhibiting stable electrical properties (e.g., leakage current and ESR) in a wide variety of operational conditions is provided. The capacitor contains an oxidized anode body and a conductive polymer coating overlying the anode body. The conductive polymer coating contains multiple layers formed from a dispersion of pre-polymerized conductive polymer particles. Unlike conventional attempts, the present inventors have surprisingly discovered that capacitors formed from such conductive polymer dispersions can operate at high voltages, and also achieve good electrical performance at relatively high humidity and/or temperature levels. More particularly, the present inventors have discovered that the problem of layer delamination may be overcome by carefully controlling the configuration of the conductive polymer coating and the manner in which it is formed. Namely, the coating contains a first layer that only partially covers the anode body. Because the anode body is not completely coated, the gaseous bubbles generated within the first layer are able to more easily escape via the uncoated portion without tearing away portions of the polymer layer. This minimizes the subsequent formation of surface inhomogeneities that could otherwise lead to delamination. The coating may likewise contain a second layer that overlies the first layer, and covers substantially the entire surface of the anode body.
