<p>The present invention discloses a radial lead aluminum electrolytic capacitor comprising: a wound unit (5), a case (6) provided with an opening (8) and containing the wound unit (5) impregnated by electrolyte; and a seal (7) for sealing up the opening (8) of the case (6). The wound unit (5) comprises: a cathode foil (3') which is a cathode formed foil; an anode foil (3); a first separator (4'); a second separator (4); a first lead wire (1') stitched to the cathode foil (3'); and a second lead wire (1) stitched to the anode foil (3); and is formed by winding a lamination made by these elements. Gasket formed foil(s) (2',2) may be arranged at the stitching places of the first lead wire (1') and the second lead wire (1) or only at a stitching place of the first lead wire (1'). The radial lead aluminum electrolytic capacitor is resistant to inverse voltage and higher temperature, and sequentially resistant to high ripple current and has more times of charging/discharging.</p> |
