0402 chip resistors are high-precision and high-stability resistors, with a power of 1/16w, a working voltage of 50V, and a working temperature range of -55--+125℃. Commonly used in ASIC miner hash board, control board repair. It can also be used in electronic products such as hard drives, portable DVD players, wireless headphones, etc. The 0402 chip resistor has high power, high precision, and good stability, with a resistance error of ±0.5% and a temperature coefficient of ±50ppm/℃.

A resistor is an electronic component that hinders current, while an SMD resistor is the abbreviation of a chip fixed resistor, which is one of the metallic glass uranium resistors. It is a resistor made by mixing metal powder and glass uranium powder and printing it on the substrate by screen printing. Chip resistors have the characteristics of moisture resistance, high-temperature resistance, and small temperature coefficient, which can greatly save the cost of circuit space and make the design more refined. This has also become one of the reasons why it is widely used in the field of electronic consumption.
