Electronic components are components of electronic components and small machines and instruments. They are often composed of several parts and can be used in similar products; they often refer to certain parts of electrical appliances, radios, instruments and other industries, including capacitors, transistors, A general term for electronic devices such as hairsprings and springs. Common ones are diodes.
　　Electronic components include: resistors, capacitors, inductors, potentiometers, tubes, heat sinks, electromechanical components, connectors, semiconductor discrete devices, electroacoustic devices, laser devices, electronic display devices, optoelectronic devices, sensors, power supplies, switches, micro Special motors, electronic transformers, relays, printed circuit boards, integrated circuits, various circuits, piezoelectric, crystal, quartz, ceramic magnetic materials, substrates for printed circuits, special materials for electronic functional processes, electronic adhesive (tape) products , electronic chemical materials and parts, etc.
　　In terms of quality of electronic components, there are international certifications such as CE certification of the European Union, UL certification of the United States, VDE and TUV certification of Germany, and CQC certification of China to ensure the qualification of components.
