Before understanding the technical indicators of potentiometer selection, let's first understand the working principle of the potentiometer.

The potentiometer is an adjustable electronic component. It is composed of a resistor body and a rotating or sliding system. When a voltage is applied between the two fixed electric shocks of the resistor body, the position of the contact on the resistor body can be changed by rotating or sliding the system, and a corresponding position of the movable contact can be obtained between the movable contact and the fixed contact. A certain relationship of voltage. It is mostly used as a voltage divider, which is a four-terminal component of the potentiometer. The potentiometer is basically a sliding rheostat, there are several styles, generally used in the speaker volume switch and laser head power size adjustment potentiometer is an adjustable electronic component. It is composed of a resistor body and a rotating or sliding system. When a voltage is applied between the two fixed electric shocks of the resistor body, the position of the contact on the resistor body can be changed by rotating or sliding the system, and a corresponding position of the movable contact can be obtained between the movable contact and the fixed contact. A certain relationship of voltage.

There are various suppliers and potentiometer models in the potentiometer market. What are the important technical reference indicators for choosing a potentiometer?

Among the technical reference indicators of potentiometers, linearity and life are the main technical indicators. The quality of linearity and life can represent the technical ability of a potentiometer manufacturer. Good linearity can guarantee a standard signal to avoid the occurrence of jumping phenomenon; long-life potentiometers are used in special occasions, such as motors, sensors, and large-scale mechanical controls. Beijing mobile phone signal amplifiers are installed.

First, linearity.

Second, life span. The life of the potentiometer has a great relationship with the material. If the material is a conductive plastic film, the life is generally very high.

third. power. The power is constantly changing with the temperature. The higher the temperature, the lower the power. So if your instrument's working temperature is high, you must choose a correspondingly larger potentiometer. Some devices need to use a high-power potentiometer as a control Part of it is used to absorb power, such as teaching equipment, electrical equipment and instruments.
