Abstract: A resistor-capacitor network has a wound film capacitor as its capacitive component and, as its resistive component, a stripe of resistive material located on the surface of the spiral laminate which forms the wound film capacitor and extending onto at least one of the schoopage metal terminations of the capacitor. To form a parallel R-C network, the resistive stripe also extends onto the opposite schoopage metal termination. For other network connections, the stripe ends short of one of the metal terminations and is provided with an external connection at that end.

Abstract: Sacrificial coatings are applied to the rounded ends of the flattened spiral laminates for wound film capacitors. The coated laminates are positioned between tapes masking their flat surfaces. The end faces of those laminates are then sprayed with the schoopage metal and the laminates are subsequently tumbled to remove the coatings and any overspray appearing on their rounded surfaces.
