  • Patent number: 8300387
    Abstract: A capacitor assembly that is thermally and mechanically stable in high temperature environments is provided. Thermal stability is provided by enclosing and hermetically sealing the capacitor element within a housing in the presence of a gaseous atmosphere that contains an inert gas, thereby limiting the amount of oxygen and moisture supplied to the solid electrolyte of the capacitor. To provide the assembly with good mechanical stability, a polymeric restraint is also employed that is positioned adjacent to and in contact with one or more surfaces of the capacitor element. Without intending to be limited by theory, it is believed that the strength and rigidity of the polymeric restraint can help the capacitor element better withstand vibrational forces incurred during use without resulting in delamination. In this manner, the capacitor assembly is able to better function in high temperature environments.

  • Patent number: 8279583
    Abstract: A solid electrolytic capacitor containing a capacitor element that includes an anode, dielectric layer, and solid electrolyte is provided. The anode is formed from a plurality (e.g., two or more) of separate components, which allows the properties of each component (e.g., density, quality, etc.) to be more readily controlled during manufacturing. The components are electrically connected using a refractory metal paste (e.g., tantalum paste) that sinter bonds to the components to form a strong and reliable connection. The ability to reliably bond together separate components enables the use of a wide degree of possible cross-sectional profiles for each individual component. For example, the components may posses a relatively complex profile that contains one or more indentations and/or projections for increasing surface area. Despite the complex profile, the components may be readily connected to each other in accordance with the present invention to form the anode.

  • Patent number: 8259435
    Abstract: A wet electrolytic capacitor that contains a hermetically sealed lid assembly is disclosed. More specifically, the lid assembly contains a lid (e.g., titanium) that defines an internal orifice. A conductive tube may extend through the orifice that is of a size and shape sufficient to accommodate an anode lead. An insulative material is also provided within the orifice to form a hermetic seal (e.g., glass-to-metal seal), such as between the conductive tube and the lid. The lid assembly also includes a liquid seal that is formed from a sealant material. The liquid seal coats a substantial portion of the lower surface of the lid and hermetic seal to limit contact with any electrolyte that may leak from the casing. To help achieve such surface coverage, the sealant material is generally flowable so that it can be heated during production of the capacitor and flow into small crevices that would otherwise remains uncoated.

  • Publication number: 20120154984
    Abstract: An electrolytic capacitor in which a capacitor element can be fixed firmly into a metal case without having adverse effects on the electrical characteristics of the electrolytic capacitor. An anode foil provided with an anode internal terminal and a cathode foil provided with a cathode internal terminal are wound or laminated through a separator to produce a capacitor element. The capacitor element is then contained in a metal case together with a driving electrolyte, and then the side surface of the metal case is caulked to press and fix the capacitor element, thus producing an electrolytic capacitor. The electrolytic capacitor is characterized in that a tape material is wound by a plurality of turns around the outer circumference of the capacitor element between the capacitor element and the caulking of the metal case such that a total thickness of the tape material is so large as to relax deformation of the capacitor element when the side surface of the metal case is caulked.

  • Publication number: 20120075775
    Abstract: A capacitor containing a solid electrolytic capacitor element that includes an anode, dielectric, and solid electrolyte is provided. An anode lead extends from the anode and is electrically connected to an anode termination. The anode termination contains an upstanding portion that is bent or folded about an axis so that it possesses two or more sections. A slot (e.g., U-shaped) extends through the sections of the upstanding portion for receiving an anode lead. The resulting “folded” configuration of the anode termination increases the total thickness of the upstanding portion and its associated slot, which thereby enhances the degree of mechanical support and stability that the termination provides to the anode lead. This is particularly beneficial for thicker anode leads, such as those having a height and/or width of about 100 micrometers or more, in some embodiments about 200 micrometers or more, and in some embodiments, from about 250 to about 1000 micrometers.
