Latest Patents

Shirakawa's latest patents include two distinct designs for solid electrolytic capacitors. The first patent describes a solid electrolytic capacitor that features a capacitor element laminate, which includes capacitor elements, cathode lead-out layers, and a sealing body. This design ensures that at least one of the capacitor elements contains an anode foil, dielectric layers, and cathode layers. The first external electrode connects to the anode foil exposed at the first end surface of the capacitor element laminate, while the second external electrode connects to the cathode lead-out layers exposed at the second end surface. The sealing body is composed of a first and second resin molded body, both made from the same insulating material.

The second patent also focuses on a solid electrolytic capacitor, which consists of multiple laminated units. Each unit includes a valve action metal substrate with a porous layer, a dielectric layer, and a solid electrolyte layer. A metal foil is positioned between the laminated units, and the entire assembly is sealed with a coating resin. The valve action metal substrate has an anode section-side end surface that connects directly to an anode outer electrode, while the metal foil connects to a cathode outer electrode on the surface of the coating resin.
