Abstract

The invention discloses a high-energy tantalum hybrid capacitor and an assembly process for the capacitor. The anode lead wire of the insulator includes a tantalum tube, the tantalum tube is a hollow structure, and the lower end surface of the tantalum tube is flush with the lower end surface of the insulator cover; In the above capacitor, the anode tantalum wire is directly drawn from the end face of the anode core block, passes through the isolation layer one and the insulating gasket, and is welded to the tantalum tube at the tantalum tube opening of the insulator tantalum tube. Compared with the prior art, the capacitor of the present invention removes the opening pad, and the anode tantalum wire is directly led out from the end face of the anode core block, and the anode tantalum wire does not occupy space at the height of the capacitor. Compared with the original structure, the overall height of the new structure in the present invention can save 1.5-2 mm of space, and the saved space can be used for expanding the anode core block of the capacitor, thereby greatly increasing the capacitance of the capacitor itself. The assembling process is improved on the prior art, the method is simple, and the assembling effect is good.
