The utility model provides a novel high-power chip resistor, which comprises a skeleton, a positive contact plate, a negative contact plate and a resistance layer. One end of the skeleton is provided with a positive contact plate, the other end of the skeleton is provided with a negative contact plate, and the surface of the skeleton is provided with a resistance layer. One end of the resistance layer is welded on the positive contact plate, and the other end of the resistance layer is welded on the negative contact plate. The beneficial effect of the model is: simple structure, high temperature resistant insulation board as the resistor skeleton, light material, sheet shape is more conducive to saving installation space, greatly reducing the weight and occupying space of a single resistor; only need to winding resistor wire or resistance coating on the skeleton surface, and spot welding at the two poles of the resistor, the process steps are greatly reduced, and the manufacturing process is simple. It greatly improves the production efficiency, and has no coating on the surface, no odor and smoke when used, so as to avoid affecting the environment.
