Electronic Component Parts

Electronic components Parts are the basic elements in electronic circuits, usually individual packages, and have two or more leads or metal contacts. Electronic components must be connected to each other to form an electronic circuit with specific functions, such as amplifiers, radio receivers, oscillators, etc. One of the common ways to connect electronic components is soldering to printed circuit boards. Electronic components may be individual packages (resistors, capacitors, inductors, transistors, diodes, etc.), or groups of various complexity, such as integrated circuits (operational amplifiers, exclusions, logic gates, etc.).

Component classification
In order to maintain the stability of the operation of electronic components, they are usually covered and packaged with synthetic resin (Resin dispensing) to improve insulation and protection from environmental influences. [1]
Components may be passive or active:
Passive components are electronic components that do not have any gain or directionality when in use. In network analysis, they are called electrical elements.
Active components are a kind of electronic components. Compared with passive components, they have gain or directionality when in use. They include semiconductor devices and vacuum tubes.
