Understanding and function of electronic components

The understanding and function of electronic components are as follows:

I. Understanding of Electronic Original

Electronic components are the foundation of electronic products. Knowing the types, structures and properties of common electronic components and choosing them correctly is the basis of learning and mastering electronic technology.

Commonly used electronic components are: resistors, capacitors, inductors, potentiometers, transformers, etc. As far as installation methods are concerned, it can be divided into traditional installation (also called through-hole installation (DIP)) and surface installation (also called SMT or SMD). Triode and diode are called electronic devices.

In order to maintain the stability of electronic components, they are usually encapsulated with synthetic resin to improve insulation and environmental protection. An element can be passive or active.

Second, how to understand the role of electronic components

1, electronic components are the basis of electronic products, commonly used electronic components are: resistors, capacitors, inductors, potentiometers, transformers, triodes, diodes, etc. As far as installation methods are concerned, it can be divided into two categories: traditional installation and surface installation.

2. The main function of resistor is to prevent current from flowing, and it is applied to current limiting, shunt, step-down, voltage division, load and capacitor matching as filters and resistor matching. Its functions in digital circuits include pull-up resistance and pull-down resistance.
