Electronic products have been very popular in our daily life and occupy a very important position in our life, such as mobile phones, computers, televisions, etc. these devices are composed of tens of thousands of electronic components. Therefore, we ignore its existence. What are the commonly used electronic components? Let's have a look today.

1、 Common electronic components

First, let's take a look at the common electronic components. Generally, common electronic components include: capacitors, resistors, inductors, potentiometers, diodes, triodes, tubes, relays, transformers, connectors, various sensitive components, resonators, filters, switches, etc.

2、 Top 10 list of common electronic components

Next, let's continue to look at the top 10 ranking of common electronic components and see which components can become the boss.

No. 10: transformer. The working principle of transformer is a device that uses the principle of electromagnetic induction to change the AC voltage. It plays the role of voltage rise and fall in electrical equipment, and also has the functions of matching impedance, safe isolation and so on.

No. 9: sensor. Sensor (English Name: transducer / sensor) is a kind of detection device. It can feel the measured information and transform the sensed information into electrical signal or other required forms of information output according to a certain law, so as to meet the requirements of information transmission, processing, storage, display, recording and control. In order to obtain information from the outside world, people must rely on sensory organs. However, it is far from enough to rely on people's own sensory organs in the study of natural phenomena, laws and production activities. In order to adapt to this situation, sensors are needed. Therefore, it can be said that the sensor is the extension of human facial features, also known as electric facial features.

No. 8: FET. The full name of field effect transistor (FET) is a semiconductor device that uses the electric field effect of the input circuit to control the output circuit current. FET can be used for amplification, variable resistance, constant current source, electronic switch, high input impedance, and is very suitable for impedance conversion

Field effect transistor

No. 7: crystal triode. Crystal triode is a semiconductor device that controls the current and can amplify the current. Its function is to amplify the weak signal into an electrical signal with large amplitude value; It is also used as a contactless switch to control various electronic circuits.

Crystal triode

No. 6: varactor. Varactor diodes (English Name: varactor diodes), also known as' variable reactance diodes', is made by using the characteristics that the junction capacitance changes with the applied voltage when the PN junction is reverse biased. It is used as a variable capacitor in high-frequency tuning, communication and other circuits.. It is used as automatic tuning, frequency modulation and equal modulation in high-frequency circuit, such as variable capacitance in the tuning loop of TV receiver.

Varactor diode

No. 5: inductor. Inductance is an attribute of closed loop and a physical quantity. When the coil passes through the current, a magnetic field induction is formed in the coil, and the induced magnetic field will generate induced current to resist the current passing through the coil; Inductor (English Name: inductor) is an inductive component made of inductive properties. If the inductor is in the state of no current, it will try to prevent the current from flowing through it when the circuit is connected; If the inductor is in a state of current flow, it will try to keep the current constant when the circuit is disconnected. Inductor is also called choke, reactor and dynamic reactor.

Inductor

No. 4: zener diode. Zener diode (English name zener diode) is a diode with voltage stabilizing effect, which is made by using the reverse breakdown state of PN junction, its current can change in a large range and the voltage is basically unchanged. This diode is a semiconductor device with high resistance until the critical reverse breakdown voltage At this critical breakdown point, the reverse resistance decreases to a small value. In this low resistance region, the current increases and the voltage remains constant. The zener diode is divided according to the breakdown voltage. Because of this characteristic, the zener tube is mainly used as a voltage regulator or voltage reference element. Zener diodes can be connected in series for use at higher voltage. Higher stable voltage can be obtained by connecting in series.

No. 3: crystal diode. Crystal diode (English Name: crystal diode) is a semiconductor device in solid-state electronic devices. The main characteristic of these devices is that they have nonlinear current voltage characteristics. Since then, with the development of semiconductor materials and technology, a variety of crystal diodes with various structures and functions have been developed by using different semiconductor materials, doping distribution and geometric structure. Manufacturing materials include germanium, silicon and compound semiconductors. Crystal diodes can be used to generate, control, receive, transform, amplify signals and convert energy. Crystal diodes are widely used in electronic equipment, but they can only rank third in the list of common electronic components.

Crystal diode

No. 2: capacitor. Capacitors are usually referred to as capacitors for short. Capacitor, as the name suggests, is a "container for electricity", which is a device that contains electric charge. Capacitor is one of the electronic components widely used in electronic equipment. It is widely used in circuit isolation, direct intersection, coupling, bypass, filtering, tuning loop, energy conversion, control and so on.

capacitor

Capacitors are widely used in electronic equipment, but they can only rank second in the list of common electronic components. Now it's time to witness miracles.

1st place: resistor. Resistor (English Name: resistor) is generally directly called resistance in daily life. It is a current limiting element. Resistance can hinder the current. It can limit the current through the branch connected to it. The current can be adjusted through the resistance of the resistor, so as to ensure the stable operation of various components in the electronic equipment under the rated current. Although the function of resistance is very ordinary, it is of great significance. With resistance, the safety of various components can be guaranteed.

resistor

Unexpectedly, the resistor ranks first. Yes, the resistor ranks first in the list of common electronic components. In the electronic industry, no one knows the resistor, and its importance is beyond doubt; It can be said that the resistor is the most used electronic component in all electronic circuits.
