What are electrical components?

‌Electrical components include many types, mainly electronic components and electronic devices. ‌Electronic components are the basic elements of electronic circuits. They are usually individually packaged and have two or more leads or metal contacts, which are used to connect to form electronic circuits with specific functions, such as amplifiers, radio receivers, etc. Common electronic components include resistors, capacitors, inductors, potentiometers, etc. ‌

‌Electronic devices include diodes, triodes, optoelectronic devices, electroacoustic devices, display devices, thyristors, field effect transistors, IGBTs, relays, reed switches, sensors, SMD components and integrated circuits, etc. ‌ These devices play a key role in electronic equipment. For example, the unidirectional conductivity of diodes makes them widely used in rectification, isolation, voltage regulation, etc. ‌

‌Common electrical components also include contactors, fuses, time relays, circuit breakers, travel switches, transfer switches and proximity switches, etc. ‌ These devices play the role of connecting, disconnecting, protecting and controlling in the circuit, and are widely used in power load and equipment protection.
