Rotary Potentiometer – Linear

The Rotary Potentiometer is a linear variable resistor designed for analog voltage control and signal adjustment in electronic circuits. It provides smooth and accurate resistance variation through a rotating shaft mechanism, making it suitable for voltage division, analog input control, and signal tuning applications. With a maximum power rating of 0.5W and operating voltage up to 200V, it delivers stable and reliable performance across a wide range of projects. Commonly used for LED dimming, audio volume control, PWM adjustment, and microcontroller ADC interfacing in embedded and DIY electronics systems.
