Chongqing electronic components market is located at No.22 Xinhua Road.
Electronic components are components of electronic components and small machines and instruments, which are often composed of several parts and can be used in similar products. It often refers to some parts of electrical appliances, radios, meters and other industries, and is the general name of electronic devices such as capacitors, transistors, hairsprings and clockwork. Common ones are diodes and so on.
electronic components include: resistors, capacitors, inductors, potentiometers, electron tubes, radiators, electromechanical components, connectors, semiconductor discrete devices, electro-acoustic devices, laser devices, electronic display devices, photoelectric devices, sensors, power supplies, switches, micro-special motors, electronic transformers, relays, printed circuit boards, integrated circuits, various circuits, piezoelectricity, crystals, Shi Ying, etc.
history of development
the history of electronic components is actually a condensed history of electronic development. Electronic technology is a new technology developed at the end of the 19th century and the beginning of the 2th century. It developed most rapidly and was widely used in the 2th century, and became an important symbol of the development of modern science and technology.
in p>196, the American inventor deforest invented the vacuum triode (electron tube). The first generation of electronic products centered on electron tubes. At the end of 194s, the first semiconductor triode was born in the world. It was used by many countries for its small size, portability, power saving and long service life, and replaced the electron tube in a large range.
in the late 195s, the first integrated circuit appeared in the world, which integrated many electronic components such as transistors on a silicon chip, making electronic products more miniaturized. Integrated circuits have developed rapidly from small-scale integrated circuits to large-scale integrated circuits and ultra-large-scale integrated circuits, thus making electronic products develop in the direction of high efficiency, low consumption, high precision, high stability and intelligence.
