<p>A wound capacitor comprises a winding having a pair of ends (24, 26) and includes first, second and third insulative layers (28, 30, 32) each extending substantially from one end (24) of the winding to the other end (26) of the winding. A first electrode (34) is disposed between the first and second insulative layers (28, 30) and a second electrode (36) located between the second and third layers (30, 32). A third electrode (38) is positioned on the side of the third layer (32) away from the second electrode (36). The first electrode (34) extends to one end (24) of the winding and short of the other end (26) while the third electrode (38) terminates short of the one end (24) but extends to the other end (26). The second electrode (36) terminates short of both ends (24, 26) of the winding. A conductive tab (44) electrically connects the second electrode (36) with a tab (42) extending beyond a winding end and is insulated at the location where it passes that winding end. A conductive coating covers each of the winding ends (24, 26) so that contact with the first and third electrodes (34, 38) is through respective ends of the winding while contact with the second electrode (36) is through the conductive tab (44). A method of winding such a capacitor is also disclosed.</p> |
