What should pay attention to in the application of the potentiometer?

1.The name of the potentiometer is relatively simple, because the synthetic membrane potentiometer is widely used, the distribution characteristics of the resistance value are mainly seen on the model. In the model, W denotes the potentiometer, and H denotes the synthetic membrane.

2.In many cases, the potentiometer is not interchangeable, it is necessary to use the same type of potentiometer to instead of.

3.In the replacement of potentiometer, pay attention to the installation dimensions of the potentiometer.

4. Some potentiometers, in addition to each pin, also have a pin on the metal shell of the potentiometer to be used as the ground wire of the circuit board, in order to eliminate the inductive interference of the human body when the potentiometer is adjusted.

5.The common fault of the potentiometer is the rotational noise, and almost all the potentiometers are used for a period of time, and the rotational noise will appear to varying degrees. Usually, the movable plate contact and the carbon membrane body of the potentiometer are cleaned. To eliminate the noise. For the noise caused by the abrasion of the carbon film body, it is necessary to replace the potentiometer.
