Feel the charm of electronic components

The charm of electronic components lies in their contribution to the design of integrated circuit products, advanced and characteristic chip manufacturing technology, advanced packaging, testing technology, key equipment, instruments, new generation semiconductor materials and device technology. The output has accounted for nearly 39% of the world's total. The products with the highest output in the world are: capacitors, resistors, electro-acoustic devices, magnetic materials, piezoelectric quartz crystals, micro-motors, electronic transformers, printed circuit boards.

With the expansion of China's electronic information industry, the four major electronic information industry bases in the Pearl River Delta, the Yangtze River Delta, the Bohai Bay region, and some central and western regions have taken shape. The electronic information enterprises in these regions are concentrated, the industrial chain is relatively complete, and they have considerable scale and supporting capabilities.

It is classified as a resistor: the resistor is represented by a "R" plus a number in the circuit, such as: R1 represents a resistor numbered 1. The main functions of the resistor in the circuit are: shunt, current limit, voltage division, offset, etc. Capacitors: Capacitors are generally indicated by a "C" plus a number in the circuit (for example, C13 represents a capacitor numbered 13). The capacitor is an element consisting of two metal films abutting and separated by an insulating material. The characteristics of the capacitor are mainly DC-blocking AC. The size of the capacitor indicates the amount of energy that can be stored. The blocking effect of the capacitor on the AC signal is called capacitive reactance, which is related to the frequency and capacitance of the AC signal.
