内容提示: Computer mainboard resistance resistor Resistor is the most widely used circuit component. In the motherboard circuit, it accounts for about 30%. of the total components. The quality of the resistor has a great influence on the stability of the circuit. In the circuit, the function of the resistor is mainly used to stabilize and adjust the current and voltage in the circuit, that is, to act as a step-down.

Computer mainboard resistance resistor Resistor is the most widely used circuit component. In the motherboard circuit, it accounts for about 30%. of the total components. The quality of the resistor has a great influence on the stability of the circuit. In the circuit, the function of the resistor is mainly used to stabilize and adjust the current and voltage in the circuit, that is, to act as a step-down. Partial pressure, flow limiting, shunting, isolation, filtering, coordination with capacitors, matching and signal amplitude adjustment. Resistors use 'R'. 'RN. 'PF'. 'FS. Show. As shown in Figure 2. 15 as a common resistor in the main board. Classification of 1. resistors It can be divided into two categories: fixed resistance ship and variable resistor, according to the working characteristics of resistance ship and its role in the circuit. A constant resistance resistor called fixed resistors generally known as "". All types of fixed resistor resistance more. The main carbon resistor. Carbon resistor. Yu metal film resistors. Wire wound electric bumper: Pu resistor values can be continuously adjusted in a certain range is called a variable resistor or potentiometer variable. Cheese usually ends with adjustable resistance potentiometer. Generally three terminal adjustable. Such as the European Union 2-16 good for resistor symbol. According to the appearance shape of resistor. Generally
