Top 10 Common Electronic Components
Electronic products have become very popular in our daily life and occupy a very important position in our life, such as mobile phones, computers, TVs, etc. These devices are composed of tens of millions of electronic components. But what are the most common electronic components?
Usually, common electronic components are: capacitors, resistors, inductors, potentiometers, diodes, triodes, tubes, relays, transformers, connectors, various sensitive components, resonators, filters, switches, etc.
The following are the top 10 common electronic components:
Resistor
A resistor is a current limiting element. The resistance has a hindering effect on the current. It can limit the current through the branch it is connected to, and the current can be adjusted by the resistance of the resistor, so as to ensure that various components in the electronic equipment work stably at the rated current. Although the role of resistors is very ordinary, its significance is very important. Only with resistors can the safety of various components be guaranteed.
Capacitor
A capacitor, is a device that holds charges. Capacitors are one of the electronic components widely used in electronic equipment, and are widely used in DC blocking, coupling, bypass, filtering, tuning loops, energy conversion, control, etc. in circuits.
Crystal diode
Crystal diode is a semiconductor two-terminal device in a solid-state electronic device. The main feature of these devices is their nonlinear current-voltage characteristics. Since then, with the development of semiconductor materials and process technology, a variety of crystal diodes with various structures and functions have been developed using different semiconductor materials, doping distributions, and geometric structures.
Crystal diodes can be used to generate, control, receive, transform, amplify signals, and perform energy conversion. Crystal diodes are widely used in electronic equipment.
Zener diode
Zener diode is a diode made of a voltage stabilizing diode that uses the reverse breakdown state of the pn junction, and its current can vary in a wide range while the voltage remains 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, and the current increases in this low resistance region. The voltage remains constant, and Zener diodes are graded according to the breakdown voltage.
Because of this characteristic, Zener diodes are mainly used as voltage regulators or voltage reference components. Zener diodes can be connected in series for use at higher voltages, and higher stable voltages can be obtained through series connection.
Inductor
Inductance is a property of a closed circuit and a physical quantity. When the coil passes current, a magnetic field induction is formed in the coil, and the induced magnetic field will generate an induced current to resist the current passing through the coil. Inductors are inductive components made of inductive properties.
If the inductor is in a state where no current is flowing, it will try to prevent current from flowing through it when the circuit is turned on. If the inductor is in a state where current is flowing, it will try to maintain the current when the circuit is opened. Inductors are also called chokes, reactors, and dynamic reactors.
Varactor diode
Varactor diodes, also known as variable reactance diodes, are made by utilizing 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 in high-frequency circuits for automatic tuning, frequency modulation, tuning, etc., for example, as a variable capacitor in the tuning circuit of a TV receiver.
Transistor
A transistor is a semiconductor device that controls current and can amplify current. Its function is to amplify weak signals into electrical signals with larger amplitude values; it is also used as a non-contact switch to control various electronic circuits.
Field effect transistor(FET)
Field effect transistor (FET), is a semiconductor device that uses the electric field effect of the control input circuit to control the output circuit current. Field effect transistors can be used for amplification, variable resistors, constant current sources, electronic switches, and high input impedance, which are very suitable for impedance transformation.
Sensor
A sensor (transducer/sensor) is a detection device that can sense the measured information and convert the sensed information into electrical signals or other required forms of information output according to certain rules to meet the needs of information transmission, processing, storage, display, recording and control requirements.
In order to obtain information from the outside world, people must rely on sensory organs. However, relying on people’s own sensory organs alone is far from enough for their functions in the study of natural phenomena and laws and production activities. To accommodate this situation, sensors are needed.
Transformer
The transformer is a device that uses the principle of electromagnetic induction to change the AC voltage. It plays the role of raising and lowering the voltage in electrical equipment, and also has functions such as matching impedance and safety isolation.
