Abstract: An X-Y condenser having an X-capacitance and two Y-capacitances, for example, for connection as a line filter, has a base winding of metallized dielectric foil strip on which a pair of axially spaced auxiliary windings are applied. A deposited metal contact at each end connects each Y-capacitance winding with the X-capacitance winding while a metal deposit between the Y-capacitance windings forms a common contact therewith.
