Ten common electronic components, what are they?

Electronic products has been very popular in our daily life occupy very important position in life, such as: mobile phone, computer, TV, etc., these devices there are thousands of electronic components, therefore, we ignore the existence of it, usually what we commonly used electronic components, we together and see it today.

I. Common electronic components

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

Top 10 Commonly used electronic components

Next, let's take a look at the top 10 most commonly used electronic components and see which ones take the top spot.

Ten common electronic components, what are they?

No. 10 transformers. Transformer (English name: Transformer) is the working principle of the use of electromagnetic induction principle to change the AC voltage device, in the electrical equipment plays the role of voltage rise and fall, and there are matching impedance, safety isolation and other functions.


9. Sensors. Transducer (English name: transducer/sensor) is a detecting device which can feel the measured information and convert the information into electrical signal or other required information output according to certain rules to meet the requirements of information transmission, processing, storage, display, recording and control. In order to obtain information from the outside world, people have to rely on sense organs. However, it is far from enough to rely on people's own sensory organs to study natural phenomena and laws as well as their functions in production activities. To accommodate this, sensors are needed. Therefore, it can be said that the sensor is the extension of human facial features, also known as electric facial features.

8. Field effect tubes. Field Effect Transistor (FET) is a semiconductor device that controls the electric Field Effect of the input circuit to control the current of the output circuit. Fets can be used for amplification, variable resistance, convenient constant current source, electronic switching, high input impedance very suitable for impedance conversion, etc

Top 7: Crystal triode. A transistor is a semiconductor device that controls and amplifies current. Its function is to amplify the weak signal into a larger amplitude of the electrical signal; Also used as a contactless switch to control various electronic circuits.

No.6: Varactor diodes. Varactor Diodes (English name: Varactor Diodes), also known as' variable reactance Diodes', is the use of pN junction reverse bias junction capacitance changes with the characteristics of applied voltage, in high-frequency tuning, communication and other circuits as variable capacitors. Used in high frequency circuits for automatic tuning, frequency modulation, phase modulation, etc., e.g. as variable capacitance in the tuning loop of a television receiver.

5. Inductors. Inductance is a property of closed loop and a physical quantity. When the coil through the current, the formation of magnetic field induction in the coil, the induction magnetic field will generate induction current to resist the current through the coil; Inductor Inductor Inductor Inductor Inductor Inductor Inductor Inductor Inductor Inductor Inductor Inductor Inductor Inductor Inductor If the inductor is in a current state, it will try to maintain the current when the circuit is disconnected. Inductor also known as choke, reactor, dynamic reactor.


Top 4: Stabilized diode. Zener diode (Zener diode) is a voltage stabilizing diode that takes advantage of the reverse breakdown state of THE PN junction, where the current can change over a wide range while the voltage is basically unchanged. The diode is a semiconductor device with very high resistance up to the critical reverse breakdown voltage. At this critical breakdown point, the reverse resistance decreases to a very small value. In this low resistance region, the current increases while the voltage remains constant. The regulator diode is graded according to the breakdown voltage. The voltage stabilizer diodes can be connected in series for use at higher voltages, by which higher stable voltages can be obtained.

Regulated diode

No. 3 Crystal diodes. Crystaldiode (English name: crystaldiode) semiconductor terminals in solid state electronic devices. The main characteristic of these devices is 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 are germanium, silicon and compound semiconductor. Crystal diodes can be used to generate, control, receive, transform, amplify signals and convert energy. Crystal diode is widely used in electronic equipment, but it can only rank third in the list of commonly used electronic components.

2. Capacitors. Capacitor is often referred to as capacitor. A capacitor, as its name suggests, is an 'electric container', a device that holds an electric charge. Capacitors are one of the most widely used electronic components in electronic equipment. They are widely used in circuit isolation, coupling, bypass, filtering, tuning loop, energy conversion, control and other aspects.


Capacitors are widely used in electronic equipment, but they only rank second in the list of commonly used electronic components. Now it's time for the miracle.

Top 1: Resistors. In everyday life, the resistors (their name is "Resistor") are simply called resistors. It is a current limiting element. Resistance to the current obstacles in effect, it can be limited by its branch of the current size, the resistance of the resistor size to adjust the size of current, to ensure all kinds of components in electronic equipment in working in the rated power flow stability, although the function of the resistance is very ordinary, but its meaning is very big, with resistance to ensure the safety of all components.

The resistor

Surprisingly, no. 1 is the resistor. Yes, the resistor is no. 1 in the list of commonly used electronic components. In the electronic industry, the resistor is known to everyone, and its importance is unquestionable; The resistor is arguably the most used electronic component of all electronic circuits.
