Various electronic products are indispensable around us in our lives. Their existence has greatly enriched our lives and made our lives rich and colorful. Normally, our functions and effects on electronic products are after using them for a long time. It can be mastered very skillfully, but has little understanding of its internal structure. Sometimes the shell of an electronic product is damaged and the circuit board is exposed. We may find it strange to see a circuit board with a peculiar appearance. However, it is difficult for us to specifically say what the components on the circuit board are and what their functions are.

In fact, in order to pursue different functions and performance of electronic products, the number and types of electronic components used on the circuit board are also different, and the production is also very complicated. Next, Chicco has a list of some common electronic components.

One, capacitance

Capacitors are generally represented by "C" plus a number in the circuit. Capacitors are components composed of two metal films close together and separated by insulating materials. Its characteristic is mainly to block the direct current and pass the alternating current. The capacity of the capacitor indicates the size of the electric energy that can be stored. The hindering effect of the capacitor on the AC signal is called capacitive reactance, which is related to the frequency and capacitance of the AC signal.

2. Resistance

Resistance is an electronic component commonly used in circuits. It has a wide range of functions in circuits. It can mainly play the role of shunting, current limiting, voltage dividing, and biasing. The larger the resistance of the conductor, the more the conductor hinders the current. The bigger it is, and vice versa.

Three, crystal diode

I believe many people have heard of the name crystalline diode, but if we want to tell us what it is, many people are confused. A crystal diode is an electronic component made of semiconductor materials. It is often represented by "D" plus a number in the circuit. Its main feature is unidirectional conductivity, that is, under the action of forward voltage, the on-resistance is very high. Small; and the on-resistance is extremely large or infinite under the action of reverse voltage.

Fourth, the inductor

Although not many inductors are used in electronic production, they are equally important in circuits. We believe that inductors, like capacitors, are also an energy storage element, which can convert electrical energy into magnetic field energy and store energy in the magnetic field. It often works with capacitors to form LC filters, LC oscillators and so on. In addition, people also make use of the characteristics of inductance to manufacture choke coils, transformers, relays, etc.

Although electronic components cannot be observed by our naked eyes from time to time, they are the key to our normal use of electronic products. It is precisely the aggregation of tiny components that can produce high-quality electronic products. But the same electronic components are very small and fragile. Once they are impacted by external forces, they are easily damaged. Secondly, electronic components are very easy to generate heat when they are working. If the heat is not dissipated in time, it may burn the electronic components. Device.
