ABSTRACT:
A nonlinear voltage resistor is formed by sintering a resistor body made from a powder predominantly comprising ZnO. The powder also includes a first element selected from the group of Li and Na and a second element selected from the group of Al, In, and Ga. The powder preferably includes 50 to 1,000 atomic ppm of the first element and a concentration of the second element sufficient to set the carrier concentration of the powder in the range of 5 atomic ppm to 120 atomic ppm.
