A solid electrolytic capacitor includes a valve metal support, a dielectric layer, a solid polymer electrolyte layer, and an insulating layer. The valve metal support has an opening formed about an anode terminal forming area except for a part of surroundings thereof. The dielectric layer is formed on a surface of the valve metal support so as to expose a part of the anode forming area. The solid polymer electrolyte layer is formed on the dielectric layer. The solid electrolytic capacitor is provided with the insulating layer for electrically insulating the anode terminal forming area in the valve metal support and the solid polymer electrolyte layer from each other.
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
