Wholesale 22mm 2K 5K 10K Plastic Rotary Potentiometer

In addition to the above characteristic parameters, the potentiometer also has parameters such as rated power, allowable resistance deviation, maximum operating voltage, rated operating voltage, insulation voltage, temperature parameters, noise electromotive force, and high-frequency characteristics. The meaning of these parameters is the same as that of the corresponding characteristic parameters of the resistor.

The potentiometer can be used as either a three terminal element or a two terminal element. The latter can be regarded as a variable resistor, which is called a potentiometer because its function in a circuit is to obtain an output voltage that is in a certain relationship to the input voltage (applied voltage). Compliance, also known as compliance, refers to the degree of compliance between the actual output function characteristics of the potentiometer and the required theoretical function characteristics. It is expressed as a percentage of the total external voltage with the maximum deviation between the actual and theoretical characteristics, and can represent the accuracy of the potentiometer.
