Chip resistor

A chip-type fixed resistor, directly translated from Chip Fixed Resistor, commonly known as SMD Resistor, 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 a substrate by screen printing. Resistant to humidity and high temperature, low temperature coefficient. It can greatly save the cost of circuit space and make the design more refined.

The chip component has small volume, light weight, high installation density and strong shock resistance. Strong anti-interference ability, high frequency characteristics, etc., widely used in computers, mobile phones, electronic dictionaries, medical electronics, camcorders, electronic watt-hour meters and VCD machines. The chip components can be divided into three types according to their shapes: rectangular, cylindrical and irregular. There are resistors, capacitors, inductors, transistors, and small integrated circuits, depending on the type. SMD components differ from the nominal methods of general components.

The application of surface mount technology (SMT) is very common, and the proportion of electronic products assembled by SMT has exceeded 90%. China has been involved in SMT technology since the 1980s. With the development of small SMT production equipment, SMT is also used in the fields of aviation, aerospace, instrumentation, machine tools and other fields to produce various electronic products or components with small quantities.
