This invention describes a packaging structure for roll-type (wound-type) aluminum conductive polymer capacitor element. Two protective substrates are applied to sandwich a roll-type capacitor element in between with an insulating material surrounding the capacitor element also in between the protective substrates. The protective substrates comprise electrically separated anodic conductive pad and cathodic conductive pad on their surfaces. The capacitor element is oriented with its axis perpendicular to the two substrates. The anodic and cathodic leads of the capacitor element pass through the through holes. An anodic external terminal is plated over the anodic conductive pad and a cathodic external terminal is plated over the cathodic conductive pad so that the anodic external terminal is electrically connected to the anodic lead and the cathodic external terminal is electrically connected to the cathodic lead. In another arrangement, the anodic and cathodic leads are bent by about 90 degree so that they point to the two sides of the packaging. External terminals are placed on the two sides of the packaging on the surfaces of the insulating material. In still another arrangement, the packaging structure uses only one protective substrate.

A substrate-type multi-layer polymer capacitor (MLPC), including a casing, a core, and two electroplated terminals. The core is arranged in an inner cavity of the casing. The casing is formed by joining two first packaging plates and two second packaging plates. The two electroplated terminals are formed by electroplating. One of the two electroplated terminals is configured to cover one end of the casing to form an anode, and the other of the two electroplated terminals is configured to cover the other end of the casing to form a cathode electrically led out from the core. The first packaging plate includes a substrate, an electrode plate and two metal plates. The electroplated terminals are integrally sealed with the casing.

To provide a hybrid capacitor with improved electrical quality and reproductivity, and to provide a method of manufacturing the same.SOLUTION: A capacitor comprises a working element. The working element comprises an anode including a first dielectric body on the anode, a cathode, and a conductive separator provided between the first dielectric body and cathode. The conductive separator comprises a separator and a first conductive polymer. The first conductive polymer at least partially encapsulates the separator. A second conductive polymer at least partially encapsulates the first conductive polymer. The first conductive polymer has a higher conductivity than the second conductive polymer. An anode lead is in electrical contact with the anode, and a cathode lead is in electrical contact with the cathode.SELECTED DRAWING: Figure 1
