An electrical resistor material comprising a dielectric polymeric binder, (optionally) electrically conductive particles, and an electrically conductive polymer, where the electrically conductive particles (if any) are used to make a positive temperature coefficient of resistance (TCR) component, and where the electrically conductive polymer is (optionally) doped, and is used to make negative temperature coefficient of resistance (TCR) component. The positive and negative components are combined at such a ratio, in the presence of a dielectric polymer binder, sufficient to provide a resistor with a sheet resistance between 0.01 and 10,000,000 ohms per square, and where the resistor has a final temperature coefficient of resistance (TCR) between −500 ppm/° C. and 500 ppm/° C. |
