Embodiment Construction
[0025] The present invention will be further described below in conjunction with the accompanying drawings.
[0026] Such as figure 1 As shown, a chip-type high-voltage miniaturized long-life aluminum electrolytic capacitor includes an outer layer of electrolytic paper 4, a positive guide pin 5, an anode foil 2, a negative guide pin 6, a cathode foil 3 and an inner layer of electrolytic paper 1. The guide pin 5 is riveted on the anode foil 2, the negative guide pin 6 is riveted on the cathode foil 3, and the outer electrolytic paper 4, the anode foil 2, the inner electrolytic paper 1 and the cathode foil 3 are wound together into a core package , the positive guide pin 5, the negative guide pin 6 and the anode foil 2, the cathode foil 3 have a piece of hydrophilic high-temperature conductive tape 7 at the riveting place; the anode foil 2 is an anode foil with high withstand voltage and high specific volume, The cathode foil 3 is a chemically formed cathode foil, and the inner...
