Ten common electronic components in print circuit boards

 Electronic products are already very popular in our daily lives, occupying very important positions in life, such as mobile phones, computers, TVs, etc. These devices are made up of tens of millions of electronic components. What are the common electronic components we often use? Let's take a look today.

1. Commonly used electronic components

First of all, let's take a look at the commonly used electronic components. Generally, commonly used electronic components are: capacitors, resistors, electric sensors, potentiocators, diodes, triode, electronics, relays, transformers, connectors, various sensitive components, resonators, filters, switches, etc.

2. the top 10 rankings of commonly used electronic components

Next, let's look at the top 10 rankings of commonly used electronic components to see which component can become the boss.

10Third place: Transformer. The working principle of the transformer is to use the principle of electromagnetic induction to change the AC voltage device, play the role of lifting voltage in electrical equipment, and also match the functions such as impedance and safety isolation.

9th place: Senior. Show, record and control requirements. In order to obtain information from the outside world, people must use the sensory organ. And people's own sensory organs alone are not enough to study natural phenomena and laws and their functions in production activities. To adapt to this situation, a sensor is needed. Therefore, it can be said that the sensor is the extension of human beings, which are also called electrical facial features.

8Third place: field effect tube. Field effect tube field effect is a semiconductor device that controls the electric field effect of the input circuit to control the output circuit current, and is named after it. The field effect tube should be used to amplify, can be used as variable resistors, can be easily used as a constant current source, can be used as an electronic switch, and can be used as a high input impedance.

7Third place: Crystal triode. Crystal triode is a semiconductor device that controls current that can escape current. Its role is to amplify the weak signal into a large electrical signal; it is also used as an unproof switch to control various electronic circuits.

Sixth place: The two poles. Diode diode, also known as "variable power resistance diode", is made of the characteristics of changing the capacitance size of the PN programming time. Used as automatic adjustment, frequency adjustment, and equal adjustment in high frequency circuits, such as making variable capacitors in the tuning circuit of a TV receiver.

5th: Electrochemical.   Inductance is a kind of property that closes the circuit and physical quantity. When the coil passes through the current, a magnetic field induction is formed in the coil, and the induction magnetic field will generate induction current to resist the current through the coil. In the state, it will try to block the current flowing through it when the circuit is turned on; if the inductor is in a state where the current is over, it will try to keep the current unchanged. The inductor is also known as a clutch, an electric anti-anti-device, and a dynamic electrical resistor.

4Third place: voltage diode. The stabilizing diode is a diode that uses the reverse breakdown state of PN programming. The current can change a large range and the voltage is basically unchanged. This diode is a semiconductor device with high resistance up to critical reverse breakdown voltage. At this critical breaking point, the reverse resistance is reduced to a small value. The voltage remains constant, and the voltage diode is divided into gear according to the breakdown voltage. Because of this characteristic, the regulator tube is mainly used as a voltage regulator or voltage reference element. The stabilized diode can be connected in series for use on higher voltages, and a higher stable voltage can be obtained by connecting in series.

3Third place: Diocese of Crystal. Eyes of semiconductor devices in solid-state electronic crystal diode devices. The main features of these devices are nonlinear current-voltage characteristics. With the development of semiconductor materials and process technology, different semiconductor materials, doping distribution, and geometric structures were used to develop a variety of crystal diodes with a variety of structures and various functional purposes. Manufacturing materials include cymbals, silicon and compound semiconductors. Crystal diode can be used to generate, control, receive, transform, amplify signals and transform energy conversion. The application of crystal diode in electronic devices is widely used, but it can only be ranked third in the ranking of common electronic components.

Number 2: Capacitor. Capacitors are usually referred to as capacitors for short. Capacitor, as the name suggests, is a container "container", a device that is accommodated. Capacitors are one of the electronic components used in many electronic devices. They are widely used in circuits for cross-pass, coupling, bypass, filtering, tuning circuit, energy conversion, control and other aspects of the circuit.

The application of capacitors in electronic devices is extremely widely used, but it can only be ranked second in the ranking of common electronic components. The time to witness the miracle is here.

1st place: resistor. The resistor is usually called a resistor directly in daily life. It is a current limiting element. Resistance is a hindrance to the current. It can limit the current size of the auxiliary circuits that can be adjusted by the resistance of the resistor to ensure that the various components in the electronic device are stable. Although the role of resistance is ordinary, its significance is very significant. With resistance, it can ensure the safety of each component.

Not surprisingly, the first is the resistor. Yes, the first one in the ranking of common electronic components is the resistor. In the electronics industry, the resistor is unknown and unknown, and its importance is beyond doubt; it can be said that the resistor is the most used electronic component of all electronic circuits.
