The appearance of adjustable resistors and general resistors is very different. The adjustable resistor has some unique characteristics, and the adjustable resistor can be easily identified in the circuit board.

First, adjustable resistors on the material can be divided into carbon film adjustable resistors and ceramic adjustable resistors;

Secondly, there will be an adjustment rotating port on the adjustable resistor, and the moving piece can be changed with a screwdriver to adjust the resistance;

Third, the adjustable resistance is larger than the ordinary resistance, and there are fewer variable resistances in the circuit, and it is easy to find the adjustable resistance in the circuit board;

4. The resistance value marked by him can be seen on the adjustable resistor. The resistance value refers to the resistance value between the two stator pins, that is, the maximum value between the stator pin and the movable pin. Value;

Fifth, the adjustable resistor has three pins, and these three pins are different. One of them is the moving film pin, and the other two are the fixed film pins. Two fixed film pins are generally interchangeable, but the moving film pins and fixed film pins cannot be used interchangeably;

Sixth, the variable resistor with a small plastic case is smaller in volume and has a circular structure, with its three pins facing down and the resistance adjusting port facing up. Some variable resistors used in high power occasions are very large, and the moving piece can slide left and right to adjust the resistance;

Seventh. Vertical adjustable resistors are mainly used in small signal circuits. The pins are downward and mounted vertically on the circuit board. The resistance adjustment port is in the horizontal direction. Horizontal adjustable resistor pins and resistors The plane is 90 degrees vertically downward, lying on the circuit board, with the adjusting opening facing upward;
