Latest Patents

One of Obata's latest patents focuses on a solid electrolytic capacitor and the method for producing it. This innovation aims to provide a solid electrolytic capacitor where the solid electrolyte is formed at the cut end part and at the masking part to a larger thickness than in other areas. This design improves the adhesion of the solid electrolyte formed on the valve acting metal oxide film, resulting in a highly stabilized capacitor with various enhanced properties. These properties include capacitance, dielectric loss, leakage current, and short circuit defective ratio, as well as improved reflow soldering heat resistance and moisture resistance load characteristics. The production method involves forming an electrically conducting polymer on a dielectric film by carefully controlling the dipping time of the valve acting metal porous body in a solution containing a monomer and an oxidizing agent, along with specific polymerization conditions.
