In our lives, we often use a variety of electronic products, such as mobile phones, computers, TVs, etc.; but, do you know that these electrical equipment is composed of thousands of electronic components, but We ignored their existence. Let’s take a look at the commonly used electronic components that make up these electronic devices, and then make a top 10 ranking of these commonly used electronic components.
Various electronic components in mobile phones
1. Commonly used electronic components
First, let’s take a look at what are the commonly used electronic components. Generally, commonly used electronic components are: capacitors, resistors, inductors, potentiometers, diodes, transistors, electron tubes, relays, transformers, connectors, various sensitive components, resonators, filters, switches, etc.
2. Top 10 rankings of commonly used electronic components
Next, we continue to look at the top 10 rankings of commonly used electronic components to see which component can become the boss.
No. 10: Transformer. The working principle of the transformer (English name: Transformer) is a device that uses the principle of electromagnetic induction to change the AC voltage. It plays a role in raising and lowering voltage in electrical equipment, and also has functions such as matching impedance and safety isolation.
No. 9: Sensor. A sensor (English name: transducer/sensor) is a detection device that can feel the information being measured, and can transform the sensed information into electrical signals or other required forms of information output according to certain rules to meet Information transmission, processing, storage, display, recording and control requirements. In order to obtain information from the outside world, people must resort to sensory organs. However, people’s own sensory organs are far from enough in the study of natural phenomena and laws and production activities. To adapt to this situation, sensors are needed. Therefore, it can be said that the sensor is an extension of the human five sense organs, also known as the electrical five sense senses.
No. 8: Field effect tube. Field effect transistor (English name: Field Effect Transistor abbreviation (FET)), the full name of field effect transistor, is a semiconductor device that uses the electric field effect of the control input loop to control the output loop current, and is named after it. The field effect tube should be used for amplification, variable resistance, convenient use as a constant current source, electronic switch, high input impedance, and very suitable for impedance transformation.
No. 7: Transistor. A transistor is a semiconductor device that controls current and can amplify current. Its function is to amplify the weak signal into an electrical signal with a larger amplitude value; it is also used as a contactless switch to control various electronic circuits.
No. 6: Varactor diode. Varactor Diodes (English name: Varactor Diodes), also known as “Variable Reactance Diodes”, are made by using the characteristic that the junction capacitance varies with the applied voltage when the pN junction is reverse biased. It is used in high-frequency tuning, communication and other circuits. Used as a variable capacitor. . Used in high-frequency circuits for automatic tuning, frequency modulation, and equalization, for example, as a variable capacitor in the tuning loop of a television receiver.

No. 5: Inductor. Inductance is a property of a closed loop and a physical quantity. When the coil passes the current, a magnetic field is induced in the coil, and the induced magnetic field will generate an induced current to resist the current passing through the coil; an inductor (English name: Inductor) is an inductance component made of inductance properties. When there is no current through the inductor, it will try to block the current from flowing through it when the circuit is on; if the inductor is in a current through state, it will try to maintain the current when the circuit is off. Inductors are also called chokes, reactors, and dynamic reactors.
No. 4: Zener diode. Zener diode (English name Zener diode) is the use of pn junction reverse breakdown state, the current can be changed in a large range while the voltage is basically the same phenomenon, made of a diode with a voltage stabilizing effect. This diode is a semiconductor device that has a high resistance until the critical reverse breakdown voltage. At this critical breakdown point, the reverse resistance is reduced to a very small value, and the current increases in this low resistance region. The voltage remains constant, and the Zener diode is divided according to the breakdown voltage. Because of this characteristic, the Zener diode is mainly used as a voltage regulator or voltage reference component. Zener diodes can be connected in series for use at higher voltages, and higher stable voltages can be obtained by connecting them in series.

No. 3: Crystal diode. Crystal diode (English name: crystaldiode) A device at both ends of a semiconductor in a solid-state electronic device. The main feature of these devices is their non-linear current-voltage characteristics. Since then, with the development of semiconductor materials and process technology, using different semiconductor materials, doping distributions, and geometric structures, a variety of crystal diodes with a wide variety of structures and different functions and uses have been developed. Manufacturing materials include germanium, silicon and compound semiconductors. Crystal diodes can be used to generate, control, receive, transform, amplify signals, and perform energy conversion. Crystal diodes are widely used in electronic equipment, but they can only be ranked third in the list of commonly used electronic components.

No. 2: Capacitors. Capacitors are usually abbreviated as capacitors (English name: capacitor). A capacitor, as the name suggests, is a ‘container for holding electricity’, a device that holds electrical charges. Capacitors are one of the most widely used electronic components in electronic equipment. They are widely used in circuits such as blocking, coupling, bypassing, filtering, tuning loops, energy conversion, and control.
Capacitors are widely used in electronic equipment, but they can only be ranked second in the list of commonly used electronic components. Now the time to witness the miracle has arrived.
No. 1: Resistors. Resistors (English name: Resistor) are generally directly called resistors in daily life. It is a current limiting element. Resistor has an obstructive effect on the current. It can limit the current through the branch connected to it, and the current can be adjusted by the resistance of the resistor, so as to ensure that the various components in the electronic equipment work stably under the rated current. , Although the role of resistance is very ordinary, but its significance is very important, with resistance to ensure the safety of various components.
