Electronic Components and Electronic Devices
Electronic components refer to finished products that do not change the molecular composition during production and processing in the factory. Commonly used electronic components are: resistors, inductors, capacitors, potentiometers, transformers, etc. In terms of installation methods, they can be divided into two types: traditional installation (also known as through-hole installation or DIP) and surface installation (also known as SMT). Or SMD). Because it does not generate electrons itself, it has no control and transformation on voltage and current, so it is also called passive device. According to the classification criteria, electronic components can be divided into 11 categories.
Refers to the finished product that changes the molecular structure during production and processing in the factory. For example, transistors, tubes, integrated circuits. Because it can generate electrons, control and change voltage (current, switching, rectification, detection, oscillation and modulation, etc.), it is also called active device. According to the classification standard, electronic devices can be divided into 12 categories, which can be summarized into two parts: vacuum electronic devices and semiconductor devices.
The difference between electronic components and electronic devices:
1. The composition is different, the electronic component is a non-detachable single body, and the electronic device is a combination that can be split into several components.
2. The function is different, the electronic component has a single function, and does not work, such as a resistor, the electronic device has an integrated function, and needs to be powered, such as a chip.
