ALUMINIUM FOIL FOR ELECTROLYTIC CAPACITORS |
摘要 |
Low-voltage aluminium foil for electrolytic capacitors having an enlarged effective surface, characterized by narrow long channels which repeatedly change their directions. The overall length of the channels, which have a diameter of approximately 0.2 micron is more than 5 microns. The zones on both sides of the foil, which zones have been provided with channels, extend to substantially equal depth over the entire surface, a zone of at least 15 microns in the middle of the cross-section being of compact aluminium. This foil can be obtained by means of pulsed direct current etching. |
