The invention discloses a high-power chip resistor which comprises a ceramic substrate, a resistance layer and electrode plates, the top and the bottom of the resistance layer are fixedly connected with inner protection layers, the top of one inner protection layer is fixedly connected with a protection shell, the bottom of the other inner protection layer is fixedly connected with a heat conduction plate, the two ends of the resistance layer are fixedly connected with conductive end plates, and one side of each conductive end plate is provided with a connecting groove. Both ends of the two electrode plates are fixedly connected with a U-shaped buckle. According to the high-power chip resistor provided by the invention, the heat conduction plate, the heat dissipation plate and other structures are arranged, so that heat generated when the resistance layer works is guided and absorbed, the overall heat dissipation efficiency of the chip resistor is effectively improved, and the service life of the chip resistor is prolonged; and meanwhile, the chip resistor main body and a mounting piece are more flexible and convenient to assemble and disassemble, and automatic production is facilitated.
Description
technical field [0001] The invention relates to a resistor, in particular to a high-power chip resistor. Background technique [0002] With the continuous development of modern society, electronic products are ubiquitous, whether in our daily family life or in enterprise production, and chip resistors are often the most internal devices in electronic products. [0003] SMD resistor is a kind of metal glass uranium resistor. It is a resistor made by mixing metal powder and glass uranium powder and printing on the substrate by screen printing. The function of chip resistor is mainly divided into: voltage division , shunt, impedance matching and filtering, zero-ohm resistors, variable resistors, and special resistors. It has many advantages such as stable performance, high reliability, and low assembly cost. [0004] The existing chip resistors have poor heat dissipation performance and short service life, and when the resistor is plugged into the PCB board, it cannot realize ...
