ABSTRACT:
A precision electrical resistance network device comprising an electrically insulating substrate having at least two film electrical resistance elements supported thereon, the resistance elements having substantially the same temperature coefficient of resistance, characterized in that the device is constructed and arranged in such a way that temperature differences resulting through connection of the device in an electric circuit are minimized, which may be done by providing the substrate with heat transfer means through which heat can flow, so that a tendency for temperature differences in the film elements to occur is counteracted, and/or by twining and locating the resistance elements adjacent one another on the substrate, whereby the mean temperature of each element is substantially the same.
