18 electronic components are commonly used

Electronic components are an important part of electronic engineering, and they can be regarded as the cornerstone of electronic systems. In modern electronic technology, there are many different electronic components. However, for beginners, the following 18 electronic components are more common and it is necessary to understand.

First, the resistor

A resistor is a component used to control the current, and the resistance value in the circuit can be changed by the resistor to control the size of the current. It usually consists of a coil or carbon resistor, but it is also made of other materials, such as metal films, thick films, or thin film resistors. Resistors are widely used in various electronic devices.

2. Capacitors

A capacitor is a device that stores electrical charge. It consists of a dielectric separated simultaneously between two conductive plates. When the two terminals of the capacitor are connected to the power supply, there will be charge savings in the dielectric. Capacitors are used in power supply filtering, pulse coupling and clock circuits in various circuits.

Three, inductance

An inductor is a component that stores electrical energy in an electronic circuit. It usually takes the form of a coil. By generating a magnetic field in the coil, inductors are able to store energy and release it into the circuit, making them an important circuit component. Inductors are used in a wide variety of electronic circuits, including amplifiers, filters and oscillators.

Four, semiconductor diode

A semiconductor diode is an electronic component used to flow an electric current in one direction. It consists of two semiconductor materials (the material is usually silicon or germanium), one is an N-type semiconductor, the other is a P-type semiconductor, and the two ends are connected. When the positive electrode is connected to a P-type semiconductor, electrons flow and current can flow; When the positive electrode is connected to the N-type semiconductor, the current will be blocked. It can be used for potential conversion, amplification and rectification.

5. Transistors

A transistor is also a semiconductor component that can control large currents without consuming large amounts of power. The transistor is made of three different semiconductor materials, forming a PNP (positive-negative-positive) or NPN (negative-positive-negative) structure. Transistors are used in amplifiers, switches and oscillators.

Six, triode

A triode is also a semiconductor component, which is a special form of transistor. It consists of three semiconductor electrodes, which are the base, the emitter and the collector. Triodes can be used in applications such as amplifiers, selectors and electronic switches.

7. Field effect tubes

Often used in amplifying and switching circuits, Fets are semiconductor devices. Its construction is similar to a transistor, but unlike a transistor, a FET uses an electric field to control the movement of charge carriers. Fets have a higher input resistance than triodes, so they are often used to amplify subtle electrical signals in amplification circuits.

Diode rectifier

Diode rectifiers are commonly used to convert alternating current to direct current. It consists of multiple diodes that allow the current to flow in only one direction and enable overcurrent protection. It can be used in electronic power supplies, battery charging and industrial power supplies.

9. Transformer

A transformer is an electromagnetic component that can turn a high voltage into a low voltage or a low voltage into a high voltage. Transformers are used in many ways, such as power supplies, audio amplifiers and transformers.

10. Motors and electromagnets

Both motors and electromagnets are components that convert electrical energy into mechanical energy or magnetic effects. Motors usually consist of electric motors and generators, mainly used in production and transportation. Electromagnets are commonly used in automation and control systems.

11. Titration components

A titration device is an electronic tool used to measure voltage, current, and resistance values in a circuit. These components include digital multimeters, ammeters and equivalent devices used in audiovisual. They usually provide high precision electrical measurements and are easy to use.

12. Capacitor resistance combiner

A capacitor resistance combinator is a combination of components consisting of resistors and capacitors that can be used for filtering, signal conditioning, and amplification. They can provide customized circuit characteristics, so they can be used in many different applications.

13. Low-pass filter

A low-pass filter is a filter that can be used to weaken or remove high-frequency signals. They are widely used in audio amplifiers, anti-jamming circuits and data communication systems.

Xiv. High-pass filter

A high-pass filter is a filter that can be used to remove low-frequency signals. They are widely used in audio amplifiers, anti-jamming circuits and data communication systems.

15. Ordinary differential capacitor

An ordinary differential capacitor is an electronic component used in analog circuits. They can be used to simulate difference equations for motors, mechanical systems, and electronic networks.

16. Oscillator

An oscillator is a component that produces an oscillating signal. They can be used for precise control of voltage, current, and frequency and are therefore widely used in antennas, receivers, and voltage-controlled oscillators (VCXOs).

17, IC chip

An IC chip is a component that integrates multiple electronic devices into a single package. They are widely used in digital and analog electronic systems to provide highly integrated capabilities and reliable performance.

Eighteen, electrolytic capacitors

An electrolytic capacitor is a device that stores electrical charge. They are often used in applications that output large currents or require prolonged use. They can be used for energy storage, power supply filtering and DC voltage regulators.

In short, electronic components are an extremely important part of electronic engineering. In the daily work of electronic engineers, these components are often used to design and test circuits, as well as to solve various problems that may occur in circuits. Therefore, it is very valuable for beginners or amateurs in electronic engineering to be familiar with the basic characteristics of these components.
