Electronic components are substances capable of producing or controlling other physical quantities. It can be magnetic materials, semiconductors, optoelectronics, etc., or it can be mechanical parts.
1. Definition of electronic components
An electronic component is a device or device that converts electrical energy into other energies. These devices or devices are often called electrical components, such as transformers, capacitors, inductors, resistors and rectifiers. In addition, some people think that the electronic product itself is a specialized circuit board or chip, rather than a component. This is IXYS-CPC1017NTR. Several commonly used electronic components :1. Battery: battery is the device that converts chemical energy into electric energy, which can be used for charging and discharging. 2 capacitors: capacitors are mainly used in alternator, motor, tape recorder, television, because they have a great energy storage capacity, and the requirements are not high. 3. Resistor: resistor is widely used to adjust DC power supply system, such as voltage regulator, filter, absorber, varistor, etc. 4. Photocell: Photocell is widely used in luminous lighting products, such as laser head, LED lamp, spot lamp and so on.
2: several commonly used electronic components
Several commonly used electronic components are resistors, capacitors, inductors, semiconductors, magnetic materials and superconductors. Resistance is the most common component in electronic circuit, which is usually divided into two categories: resistor and potentiometer. Resistors can also be divided into "sheet" or "plate" two forms. In use, generally only need to connect the two resistors to complete a complete function. Resistors have the advantages of high sensitivity, low loss, long life and high reliability, and are widely used in various control equipment and automation devices in the industrial production process. Capacitors are mainly used in large capacity energy storage devices, such as batteries, motors and transformers. According to its structure, it can be divided into three types: multilayer capacitor, single-layer capacitor and thin-film capacitor.
3: Application domain
Electronic components are widely used in industry, agriculture and national defense. Common ones are resistors, capacitors, inductors, transformers, switching power supplies, sensors, relays, automotive drive motors and solar panels. These products are called "power collection devices" or "power sources" because they use electric energy to provide convenience for people. In today's society, more and more people regard electronic products as an indispensable part of their daily life. For example, mobile phones, computers, flat screen TVS and so on, they can not only talk and surf the Internet, but also help us finish work or play.
Therefore, electronic components are playing an increasingly important role in modern society. With these electronic components, people can have a more convenient life style.
