  • Patent number: 3947799
    Abstract: A printed resistor is proposed which has a laminated structure comprising a substrate and a foil current-carrying pattern attached to the substrate and provided with two current terminals and with at least one potential terminal. The current-carrying pattern is made as a network of series-parallel arms. A section of one of the parallel arms of the pattern is made of a material whose temperature coefficient of resistance exceeds that of the material of the rest of the current-carrying pattern. One side of said section is connected to one of the current terminals and the other, to one of the potential terminals. Proposed also is a method of manufacturing such printed resistors which consists in that, first, an area of the foil with a size sufficient for the temperature compensating element of the resistor to be accommodated thereon is coated with a metal layer whose temperature coefficient of resistance and the rate of solution in an etching substance are higher than those of the foil material.
