SOLID ELECTROLYTIC CAPACITOR

摘要

PROBLEM TO BE SOLVED: To provide a solid electrolytic capacitor in which the characteristics are sustained even under conditions of violent vibration. SOLUTION: The solid electrolytic capacitor 1 comprises a case 3 having one open end part, and a capacitor element 2 being contained in the case 3. The capacitor element 2 comprises a winding body 21 formed by winding an anode foil 22 and a cathode foil 23 through a separator 24 and impregnated with a solid electrolyte or provided with a conductive polymer layer. Opening of the case 3 is closed with a sealing member 4 being boded with a pair of lead pins 40 and 40 and the capacitor element 2 is connected with the lead pins 40 and 40. The sealing member 4 is provided with protrusions 5 for preventing a substrate 6 being soldered with the lead pin 40 from abutting against the joint D of the sealing member 4 and the lead pin 40.
