Electronic component type, common electronic components

Common electronic components include resistors, capacitors, crystal diodes, transformers, sensors, transistors, etc.

1. Resistors.

It is a current-limiting element. The resistance has a hindrance 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 the various components in the electronic equipment work stably under the rated current.

2. Capacitors.

It is a device that holds an electric charge. Capacitors are one of the electronic components widely used in electronic equipment, and are widely used in circuits in the field of DC blocking, bypass, filtering, tuning loop, buried energy conversion, control and other applications.

3. Crystal diode.

Semiconductor terminal devices in solid-state electronics. 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 different functions have been developed by using different semiconductor materials, doping distributions and geometric structures.

4. Transformer.

The working principle is a device that uses the principle of electromagnetic induction to change the alternating voltage, which plays the role of raising and lowering the voltage in electrical equipment, and also has the functions of matching impedance and safety isolation.

5. a sensor.

It is a kind of detection device, which can feel the measured information, and can transform the felt information into electrical signals or other required forms of information output according to the law, so as to meet the requirements of information transmission, processing, storage, display, recording and limb control.

There are many types of electrical appliances – light bulbs, motors, integrated circuits, discrete components, ......<

Electronic components include: potentiometers, electron tubes, semiconductor discrete devices, electroacoustic devices, laser devices, optoelectronic devices, etc.

1. Potentiometer.

A potentiometer is a resistive element with three pin-outs and the resistance value can be adjusted according to a certain change law. A potentiometer usually consists of a resistive body and movable brushes. When the brush moves along the resistor body, a resistance value or voltage is obtained at the output that is related to the amount of displacement.

The potentiometer can be used as both a three-terminal element and a two-terminal element. The latter can be regarded as a variable resistor, because its role in the vertical Tongzhou circuit is to obtain an output voltage that has a certain relationship with the input voltage (applied voltage), so it is called a potentiometer.

2. Electron tubes.

Electron tube is one of the earliest electrical signal amplifier devices. The cathode electron emission part, the control gate, the acceleration gate, and the anode (screen pole) lead that are enclosed in a glass container (usually a glass tube) are welded to the tube base. An electric field is used to inject an electronic modulation signal into the control gate in a vacuum, and the signal data of different parameters after amplification or feedback oscillation is obtained at the anode.

3. Semiconductor discrete devices.

Semiconductor discrete devices, generally refer to semiconductor crystal diodes, semiconductor transistors, referred to as transistors, transistors and semiconductor special devices.

4. Electroacoustic devices.

The electroacoustic device wheel refers to the device that converts electricity and sound to each other, which uses electromagnetic induction, electrostatic induction or piezoelectric effect to complete the electroacoustic conversion, including speakers, headphones, microphones, cartridges, etc.

5. Laser devices.

The light source required for optical fiber communication of laser devices should be a light source that can be modulated at high speed in order to carry large-capacity information.

6. Optoelectronic devices.

Optoelectronic devices refer to devices made according to the photoelectric effect, which are called optoelectronic devices, also known as photosensitive devices. There are many types of optoelectronic devices, but their working principles are based on the physical basis of the photoelectric effect.

Electronic components mainly include: resistors, capacitors, inductors, transformers, and semiconductors.

1. Resistors.

A resistor is a current-limiting element, after the resistor is connected to the circuit, the resistance value of the resistor is fixed, usually two pins, which can limit the amount of current through the branch it is connected to.

2. Capacitors.

Two conductors close to each other, sandwiched between a layer of non-conductive insulating dielectric, constitute a capacitor.

3. Inductors.

An inductor is a component that converts electrical energy into magnetic energy and stores it.

4. Transformer.

A transformer is a device that uses the principle of electromagnetic induction to change the alternating voltage.

5. Semiconductors.

Semiconductors are used in integrated circuits, consumer electronics, communication systems, photovoltaic power generation, lighting, high-power power conversion and other fields, such as diodes are devices made of semiconductors.

Electronic components include, but are not limited to, the following:

Resistive spine friend: A component used to limit the flow of current.

These are just some of the common electronic components, and there are actually many other kinds of electronic components. Different electronic components play different roles in electronic circuits, and a variety of different electronic functions can be achieved through their combination and connection.

In addition to the main chip, more circuit boards are used, and the more common ones are peripheral auxiliary components or general materials, such as analog devices, passive devices, etc. The components are ugly, but quality matters. In addition, fluctuations in delivery times and ** often affect the matching of the whole board.

Therefore, general materials need to pay more attention to stocking. As an authorized distributor, Fuelectronics has a complete range of general materials, active channels and sufficient inventory. Resistors, capacitors, inductors, potentiometers, tubes, radiators, electromechanical components, connectors, discrete semiconductor devices, electroacoustic devices, laser devices, electronic display devices, optoelectronic devices, sensors, power supplies, switches, micromotors, electronic transformers, relays, printed circuit boards, integrated circuits, various circuits, piezoelectric, crystals, should, ceramic magnetic materials, printed circuit substrates.

In terms of the quality of electronic components, there are CE certification of the European Union, UL certification of the United States, VDE and TUV of Germany, CQC certification of China and other domestic and foreign certifications to ensure the qualification of components. Test method: the detection of electronic components is a basic skill of home appliance maintenance, and many engineering maintenance technologies in the security industry actually come from home appliance maintenance technology, either for reference, or homogenization.

How to accurately and effectively detect the relevant parameters of the component and judge whether the component is normal is not the same thing. Different methods must be used to determine whether a part is healthy or not, depending on the part. Especially for beginners, it is necessary to master the testing methods and experience of common electronic components.
