Meaning and development of electronic components

1) Electronic components: refer to finished products that do not change the molecular composition during production and processing in the factory. Such as resistor, capacitor and inductor. Because it does not produce electrons, it has no control and transformation effect on voltage and current, so it is also called passive device. According to the classification standard, electronic components can be divided into 11 categories.

2) Electronic device: refers to the finished product that changes the molecular structure during production and processing in the factory. For example, transistors, electronic tubes, integrated circuits. Because it can produce electrons and control and transform voltage and current (amplification, 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 divided into vacuum electronic devices and semiconductor devices.

Development overview of electronic components industry:

With the rapid development of the world's electronic information industry, the electronic component industry, as the basis of the electronic information industry, is also developing very rapidly. In 2005, the demand of the world electronic components market was about US $300 billion, accounting for 15% of the world electronic products market, with an average annual growth rate of about 10%, while the demand for new electronic components grew rapidly, about US $150 billion to US $180 billion.

Electronic components are entering the era of a new generation of components with new electronic components as the main body. It will basically replace traditional components. The improvement of electronic components is mainly to meet the miniaturization of the whole machine and the requirements of new technology, but mainly to meet the characteristic requirements put forward by the development of digital technology and microelectronics technology, And it is a complete set of industrial development stage.

In recent years, China's electronic industry has maintained rapid growth, driving the strong development of chip electronic components industry. China has become the world production base of electronic components such as aluminum electrolytic capacitors and semiconductor discrete devices.
