Electronic components are a general term for components and devices. Electronic components: refers to finished products that do not change the molecular composition during production and processing in the factory. Such as resistors, capacitors, inductors. Because it does not generate electrons itself, it has no control and transformation on voltage and current, so it is also called passive device. Electronic device: A finished product that changes its molecular structure during production and processing in a factory. For example, transistors, tubes, integrated circuits. Because it can generate electrons, control and change voltage (current, switching, rectification, detection, oscillation and modulation, etc.), it is also called active device. According to the classification standard, electronic devices can be divided into 12 categories, which can be summarized into two parts: vacuum electronic devices and semiconductor devices. The history of the development of electronic components is actually a history of concentrated electronic development. Electronic technology is an emerging technology that began to develop in the late 19th and early 20th centuries. The development of the 20th century is the fastest and most widely used, and has become an important symbol of the development of modern science and technology.
The electronic components industry is mainly composed of electronic components, semiconductor discrete devices and integrated circuits.
Electronic components include: resistors, capacitors, potentiometers, tubes, heat sinks, electromechanical components, connectors, semiconductor discrete devices, electro-acoustic devices, laser devices, electronic display devices, optoelectronic devices, sensors, power supplies, switches, micro-motors , electronic transformers, relays, printed circuit boards, integrated circuits, various types of circuits, piezoelectric, crystal, quartz, ceramic magnetic materials, substrate substrates for printed circuits, electronic functional materials, electronic adhesives, electronic products Chemical materials and parts.
In terms of quality, electronic components are now certified by China's CQC, US UL and CUL certification, German VDE and TUV, and EU CE certification to ensure the qualification of components.
