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 capacitor containing a solid electrolytic capacitor element including a sintered porous anode body and a relatively large width and/or thickness anode lead tape is provided. The tape is electrically connected to the anode body for connection to an anode termination. Further, the tape has a width that is at least about 20% of the width of the anode body to improve the points of contact between the anode body and tape to reduce ESR. A portion of the tape extends from a surface of the anode body in a longitudinal direction. At least one notch can be formed in the portion of the tape that extends from the anode body. The notch can be formed via a laser or by cutting, punching, or sawing and can serve as the point of electrical connection between the anode termination and the lead tape.

摘要： A capacitor containing a solid electrolytic capacitor element having a porous anode body and an anode lead assembly is provided. At least one wire of the lead assembly is electrically connected to the anode body for connection to an anode termination. The lead assembly contains first and second lead wires embedded within the anode body and extending therefrom in a longitudinal direction. The first and second wires are bonded/fused together during sintering of the anode body (i.e., “sinter bonded”). The bond may be metallurgical, covalent, electrostatic, etc. Sinter bonding of the wires reduces the path length and resistance for current flow within the anode body, thus reducing ESR. This is particularly useful for anode bodies formed from powders of a high specific charge, which tend to shrink away from the wires after sintering. The sinter bonded wires also result in a lead assembly that is more robust and mechanically stable.

摘要： A capacitor assembly containing a solid electrolytic capacitor element and an anode lead extending in a direction therefrom, first and second cathode terminations, and an anode termination is provided. The first cathode termination contains a first portion that is substantially parallel to a lower surface of the capacitor element and in electrical contact therewith, and the second cathode termination contains a second portion that is substantially parallel to an upper surface of the capacitor element and in electrical contact therewith. Through such a “sandwich” configuration, the degree of surface contact between the cathode terminations and capacitor element is increased, which can help dissipate heat and allow it to handle higher currents that would normally cause overheating. The terminations may also provide increased mechanical support.

摘要： A capacitor containing a solid electrolytic capacitor element that includes a sintered porous anode body and an anode lead assembly is provided. The lead assembly is electrically connected to the anode body for connection to an anode termination. The lead assembly contains at least a first lead wire comprising at least one notch that is located on an embedded portion of the first lead wire. The at least one notch can be formed by crimping the lead wire prior to embedding the lead wire within the anode body. The at least one lead wire is embedded within the anode body and extends from a surface of the anode body in a longitudinal direction. The resulting geometry of the lead wire increases the points of contact between the anode body and the lead wire after post-sintering shrinkage of the anode body to improve the electrical capabilities of the solid electrolytic capacitor.

摘要： A capacitor containing a solid electrolytic capacitor element including a sintered porous anode body and a relatively large diameter anode lead wire is provided. The lead wire is electrically connected to the anode body for connection to an anode termination. Further, the lead wire has a diameter that is at least about 10% of the height of the porous anode body to improve the points of contact between the anode body and wire to reduce ESR. A portion of the lead wire extends from a surface of the anode body in a longitudinal direction. At least one notch can be formed in the portion of the lead wire that extends from the anode body. The notch can be formed via a laser or by cutting, punching, or sawing and can serve as the point of electrical connection between the anode termination and the lead wire.
