Headings H1N and H1R, [Also in Division H2] For interference suppression a capacitor 4 is connected between the terminals of an electrical device and a resistive material is cast about the capacitor and terminals, the result being a capacitance and resistance in parallel across the terminals. The terminals may first be coated with a thin dielectric layer so as to provide small capacitances in series with the resistance. The invention may be applied to solenoid-operated components such as " doll's eye " indicators and relays used in aircraft. |
