Abstract:
1. A lamellar stacked solid electrolytic capacitor, comprising: a capacitor unit composed of a plurality of negative foils, a plurality of isolation papers with conductive polymer substance and a plurality of positive foils that are alternatively stacked onto each other, wherein each isolation paper is disposed between each positive foil and each negative foil, the positive foils are electrically connected to each other, the negative foils are electrically connected to each other, and the positive foils and the negative foils are insulated from each other; a conductive layer electrically connected to one end of each negative foil, and the length of the end of each negative foil is larger than the length of one end of each positive foil in order to prevent the positive foils touching the conductive layer; a substrate unit having a positive guiding substrate electrically connected to the positive foils of the capacitor unit and a negative guiding substrate electrically connected to the negative foils of the capacitor unit; and a package unit covering the capacitor units and one part of the substrate unit.
