ELECTROLYTIC CAPACITOR

摘要

PURPOSE:To reduce influence of vibration and magnetic flux and achieving high-quality reproduction by enabling a capacitor main unit to be positioned and fixed into a cylindrical resin case with an elastic body filling agent and by fitting a metal plate at an opening opposing to an upper surface part of the metal case of the resin case. CONSTITUTION:A cylindrical resin case 14 which inner-packages a capacitor main unit 13 which is equipped with a capacitor element 11 is provided within a metal case 12 and the capacitor main unit 13 is positioned and fixed into this resin case 14 with a filling agent 15 consisting of an elastic body. A metal plate 16 is fitted to an opening opposing to an upper surface part 12a of the metal case 12 of the resin case 14. Thus, it is possible to reduce propagation of vibration for vibration from the outside with the filling agent 15 and reduce magnetic flux from an electrolytic capacitor itself or that generated from external electronic components with the metal plate 16, thus achieving a high-quality music reproduction.
