Potentiometers are essentially variable resistors, comprising resistor components with a mechanical adjustment mechanism that allows for manual modification of resistance. They are commonly used to regulate small signals or voltages.

Potentiometers, as electronic components, have undergone significant evolution over the years. Today’s market features potentiometers that are much smaller and more precise than their predecessors, available in a diverse range of types and packages. Each is specially designed to meet the specific requirements of various applications.
