What do we need to know about some passive components in SMT processing? Here you can have a comprehensive understanding of these aspects:

　　1： Inductor: The ability of a coil to store energy in a magnetic field is called an inductor, and this coil is called an inductor. The main function of inductors is to prevent interference from electromagnetic waves and filter noise in the current. They are widely used, but the technology and scale of chip inductors produced in China are still insufficient, and there is no professional manufacturer of inductors.

　　Resistor: The function of a resistor is to regulate the voltage and current in a circuit, which can be divided into three categories based on material and product packaging.

　　2： Capacitor: When two conductive substances are separated by a medium and used to store potential static electricity, it is called a capacitor. There are various types of capacitors, which can be divided into more than 30 types based on the materials used. Domestic manufacturers mainly produce aluminum electrolytic capacitors, ceramic capacitors, and plastic film capacitors.

　　3： The most common type of ceramic capacitor that investors often see in reports is the laminated ceramic capacitor (MLCC). Basically, ceramic capacitors can be divided into two types: single-layer ceramic capacitors and multilayer ceramic capacitors (MLCC). Due to its small size, large relative capacitance, low loss rate during high-frequency use, and high stability, MLCC has a promising future in response to the lightweight and short electronic products. It is mainly used in motherboards, notebook computers, mobile phones, scanners, optical drives, and modulation demodulators.
