The ground electrode forms a spark gap together with the central electrode. The resistance element contains a resistance material that contains conductive particles and non-conductive particles. At least 80% of the non-conductive particles have a maximum diameter of 20 m.

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. Blending the dielectric material with the carbon-based ink causes the modified carbon-based ink to have a resistivity that is at least double a resistivity of the carbon-based ink.
