Abstract
1424947 Capacitors SIEMENS AG 24 Jan 1974 [21 Feb 1973] 03443/74 Heading H1M A capacitor comprises polypropylene foils wound with foils of aluminium, nickel, zinc, tin, lead or alloys of these, the polypropylene foils being heat-shrunk after winding to secure connection tabs in contact with the electrodes, the tabs comprising copper coated with nickel, zinc, tin, lead, or an alloy thereof so as to avoid the deleterious effect of copper on polypropylene.
