Potentiometer – Thumbwheel Type, 25kOhm: Compact Adjustable Resistor for User Input & Control

The Thumbwheel Type Potentiometer (25kOhm) is a compact, adjustable trimpot designed for smooth and precise resistance control. With a resistance of 25kΩ and a tolerance of ±20%, this potentiometer is well-suited for applications such as user input controls, calibration, tuning circuits, and prototyping. Simply connect VCC to one outer pin, GND to the other, and use the center wiper pin to output a variable voltage that can be read by a microcontroller’s ADC. Its thumbwheel design allows for easy manual adjustment without tools, making it ideal for embedded systems, DIY electronics, and control interfaces.

Key Features

  • Resistance Value: 25kOhm nominal resistance with +-20% tolerance.
  • User-Friendly Design: Thumbwheel adjustment for quick, tool-free operation.
  • Standard Pinout: Three terminals – VCC, GND, and wiper output for easy integration.
  • Variable Voltage Output: Provides a smooth range from 0 to VCC depending on wheel position.
  • Compact Size: 3/8" round trimpot ideal for small embedded or prototyping setups.
  • Versatile Applications: Perfect for microcontroller inputs, tuning, calibration, and control knobs.
