disk a surface of which has an electrical insulation so that no tracking currents can arise between the lead throughs 4 the disk is shaped such that the region between the lead throughs 4 is nearly completely filled another improvement according to the further exemplary embodiment of fig2 is achieved by the complete embrace of the lead throughs 4 above the cover disk 1 since eddy currents that are generated by the outside wiring are thus also enabled so that a lowering of the overall inductivity results therefrom here too the metal disk 8 has an electrical insulation on its surface 9 the following inductivities were measured at 4 mhz at an aluminum electrolyte capacitor having a diameter of 75 mm and a height of 145 mm 14 0 nh without disk between the terminals and without conductive bodies in the electrolyte capacitor and 11 3 nh with conductive bodies in the electrolyte capacitor 12 5 nh with a disk between the terminals and without conductive bodies in the electrolyte capacitor and 9 5 nh with conductive bodies in the electrolyte capacitor by employing at least one conductive body in addition to the commercially available terminating disk 1 thus the inductivity can be lowered by one third the inductivity can be lowered further lt 50 by enlarging the conductive parts this being possible by integration of these metal parts into the disk as inlay parts when injecting the disk while the invention has been illustrated and described in detail in the drawings and foregoing.
