Abstract
A method includes blending a dielectric material including a titanate with a carbon-based ink to form a modified carbon-based ink. The method also includes printing the modified carbon-based ink onto a structure. The method further includes curing the printed modified carbon-based ink on the structure at a temperature that does not exceed about 250° C. In addition, the method includes processing the cured printed modified carbon-based ink to form a thick film resistor. An amount of the dielectric material blended with the carbon-based ink does not exceed about 15% by weight of the modified carbon-based ink. The modified carbon-based ink has a resistivity that is at least double a resistivity of the carbon-based ink. The thick film resistor may be configured to handle up to about 200 mA of current without fusing and/or handle up to about 1.0 W of power without fusing.
