ABSTRACT:
A film-type cylindrical resistor in which the end caps fit over the environmentally protective coating. Both the resistive film and the environmentally protective coating are applied by screen printing. Termination films are provided at the ends of the resistive film, and are electrically contacted by the end caps. The method comprises screen printing the resistive and termination films, and the environmental coating, and then mounting the end caps by interference-fit connections.
