For everyone to popularize some common components, as well as its functional characteristics, hoping to help you better understand the components. Such as: resistors, capacitors, potentiometers, electronic tubes, inductors, radiators, connectors, electroacoustic devices, laser devices, electronic display devices, optoelectronic devices, sensors, power supplies, switches, relays, printed circuit boards, integrated circuits, Crystals, quartz, ceramic magnetic materials, substrate substrates for printed circuits, special materials for electronic functional processes, etc.

Types of electronic components

Electronic components are roughly divided into the following categories:

Resistors, capacitors, inductors, transformers, semiconductors, thyristors and field effect tubes, electronic tubes and camera tubes, piezoelectric devices and Hall devices, optoelectronic devices and electroacoustic devices, surface mounting devices, integrated circuit devices, electronic display devices, Switches, connectors, relays, optocoupler devices, etc.

Functions of common electronic components

Because there are too many types of electronic components, an article cannot introduce all of them, so this article chooses several popular components to make a popular science:

Resistance

Resistors can be divided into fixed resistors and adjustable resistors. The difference between them is whether the resistance is adjustable. Resistors can also be divided into in-line resistors and chip resistors, which are distinguished by the way the resistors are installed. In addition, according to the material process classification, resistance can be divided into solid resistance, wire wound resistance, film resistance, sensitive resistance.

Inductance

Inductors can convert electrical energy into magnetic energy and store it. If the inductor is in a state where no current is passing through, 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 passing through, it will try to maintain the current when the circuit is turned off. Its main functional characteristics are DC isolation and AC, low frequency resistance and high frequency, filtering, oscillation, magnetic energy storage, etc. It is mainly divided into air-core inductors and magnetic core inductors, and is also a common electronic component.

Capacitance

A capacitor is an electronic component that holds a charge and is represented by the symbol C. The capacitor is composed of an insulating dielectric sandwiched between two metal electrodes. When a voltage is applied between two metal electrodes, the electrodes will store charge, that is, store electrical energy, so the capacitor is an energy storage element.

Diode

A diode is an electronic component that has two electrodes and allows current to flow in a single direction only, blocking current in the reverse direction. Diodes have different types of classification, according to the material can be divided into silicon diodes and germanium diodes, according to the use can be divided into rectifier diodes, zener diodes, detection diodes, light-emitting diodes, photodiodes, is the use of a wide range of electronic components.

triode

Transistors are also commonly used components in electronic circuits. Its application can be divided into linear applications and nonlinear applications. Linear applications are mainly composed of various amplifiers and linear regulated power supplies, and nonlinear applications are mainly used as various electronic switches to control the on-off of the load.

integrated circuit

Integrated circuits are very convenient to use, as long as some external resistors, capacitors and other components can achieve a certain function. There are many types, which can be divided into linear integrated circuits, digital integrated circuits and digital-analog hybrid integrated circuits. Linear integrated circuits are mainly preamplifiers, power amplifiers and various operational amplifiers. Digital integrated circuits mainly have a variety of gate circuits, flip-flops, latches, counters and so on. Commonly used digital integrated circuits are 74LS00, 74HC00, CD4000 and other series.

I hope I can help you understand more about the types of electronic components and the functional characteristics of common components.
