An introduction to commonly used electronic components written in English

Is there a text in English that seems too troublesome, and there are IC components in Chinese in detail, with the wide application and popularization of microprocessors and PCs (especially communications, industrial control, consumer electronics, etc.).

"Electronic component" can be used in English to express "electronic component". This phrase refers to the basic elements used to make electronic devices such as resistors, capacitors, inductors, transistors, diodes, integrated circuits, and many more. Some of these components are often made of semiconductor or metal materials, which can be used for signal processing, control, and transmission functions in circuits.

In addition to "electronic component", there are some other similar expressions, such as:

electronic parts: sub-parts of the electric chain, usually referring to various components and components in electronic devices.

circuit elements: circuit elements, which refer to the basic elements that make up a circuit, such as resistance, capacitance, inductance, etc.

In conclusion, "electronic components" can be expressed in English as "electronic component" or other similar phrases such as "electronic parts" and "circuit elements".

Reading guide: Electronic components are small parts that make up electronic components, machines and other equipment, it is composed of many different small parts, which can be used in various electrical appliances and instruments. Electronic components include resistors, capacitors, potentiometers, etc., which represent the development history of electronic products.

First, the development of commonly used electronic components

The development of electronic components is very rapid, in many fields have applications, the first generation of electronic components is the tube, the tube is very convenient to carry, the appearance is very exquisite, the power consumption is very small, the life of the can be used is very long, it once caused a sensation in the market. After the electron tube, there is an integrated circuit, which is composed of multiple transistors, and the emergence of this product has made electronic products enter the miniaturization. After integrated circuits, large-scale integrated circuits and ultra-large-scale integrated circuits appeared one after another.

Since then, electronic products have entered the development direction of low consumption and high precision.

2. Composition of commonly used electronic components:

1.Resistance: The unit of resistance is ohm, expressed by the letter r, and the marking method of resistance has three types: direct standard method, color ring mark and number mark method, of which the number mark method is mainly used in some small volume circuits, such as patch, and the marking method of color ring mark is widely used, such as four-color ring resistance and so on.

2.Capacitance: The letter C is the symbol of capacitance, and the capacitance is composed of two metal films close to each other, and in the middle of the two metal films are insulating materials, which separate the metal films.

The characteristic of the capacitor is that it is through the straight and straight, and the size of the capacitor is the amount of electrical energy it stores, and when the capacitor obstructs the AC signal, the resulting effect is called capacitive reactance.

3.Inductance: The letter of inductance is L, the inductance coil is composed of insulated wires and insulating brackets, the device is an insulated coil, only DC can pass through the inductance coil, the inductance is marked by two methods: direct label method and color mark method, and the unit of inductance is Heng.

3. Characteristics of commonly used electronic components: bending macro

1.Characteristics of resistor: resistor R has the function of blocking current and voltage division.

2.Characteristics of capacitance: Capacitor C can be filtered.

3.Characteristics of diodes: Diodes have the role of unidirectional conductors.

4.Embedding characteristics of light-emitting diodes: The on-point of light-emitting diodes can emit light.

5.Characteristics of triode: Triode can be used as a switch and amplifier for some electronic devices.
