US 11,935,675 B2 · Anti-surge resistor and fabrication method thereof

Abstract

An anti-surge resistor and a fabrication method thereof are provided. The current anti-surge resistor includes a substrate made by a varistor material, a resistance layer disposed on the substrate, a first terminal electrode, and a second terminal electrode. In the fabrication method of the current anti-surge resistor, at first, the substrate made by the varistor material is provided. Then, the resistance layer is formed on the substrate to provide a main body, in which the main body includes the substrate and the resistance layer, and has two opposite terminals. Thereafter, the first terminal electrode is formed on one terminal of the main body, and the second terminal electrode is formed on the other terminal of the main body.
