Novel non-solid electrolyte tantalum electrolytic capacitor

Abstract

The invention discloses a novel non-solid electrolyte tantalum electrolytic capacitor. The novel non-solid electrolyte tantalum electrolytic capacitor includes a housing, a positive electrode leading-out wire, a plunger, a ruthenium dioxide layer, a positive pole tantalum core, a fixed gasket, a negative electrode leading-out wire and an insulator, an inner wall of the housing is plated with the ruthenium dioxide layer, the positive pole tantalum core is arranged in the housing, the plunger is arranged at the top of the housing, two ends of the plunger are connected with the positive pole tantalum core and the insulator respectively, the positive electrode leading-out wire is connected to a tantalum tube of the insulator, the fixed gasket is arranged between the housing and the positive pole tantalum core, the negative electrode leading-out wire is connected to the bottom of the housing, an electronic device is arranged on the negative electrode leading-out wire, and the electronic device has a function of one-way conduction of current. After the diode is added to the negative electrode leading-out wire of the non-solid electrolyte tantalum electrolytic capacitor, when the capacitor bears reverse voltage, the diode effectively prevents reverse current from passing through the capacitor, thereby effectively preventing the capacitor from a reverse breakdown and failure.

Description

technical field [0001] The invention relates to the technical field of capacitor design and manufacture, in particular to a novel non-solid electrolyte tantalum electrolytic capacitor. Background technique [0002] With the continuous development of electronic information equipment in the direction of miniaturization and digitalization, it is required that the volume of the current metal-encapsulated solid electrolyte tantalum capacitors is continuously reduced, the installation size is continuously reduced, and the product is fixed conveniently and reliably, so as to meet the small size of aviation, aerospace, communication and other equipment. needs of transformation. During the actual use of the current non-solid electrolyte tantalum electrolytic capacitors, due to operational errors and other reasons, it is easy to cause the negative electrode of the non-solid electrolyte tantalum electrolytic capacitor to bear the positive voltage, and if the negative electrode bears th...
