Potentiometer 2W 20K ohm

The Potentiometer 2W 20K ohm is a three-terminal variable resistor with a total resistance of 20 kΩ and a power rating of 2 W. Turning the shaft moves the wiper along the resistive track, so you can adjust a voltage, set a level or control speed by hand. The 2 W rating gives more power handling than small trimmers for circuits that need it.

Potentiometer 2W 20K ohm Specifications

• Total resistance: 20 kΩ
• Power rating: 2 W
• Terminals: 3 (two track ends and the wiper)
• Maximum current through the full track: about 10 mA (√(2 W ÷ 20 kΩ))
• Quantity: 1 piece

Potentiometer 2W 20K ohm Applications

• Voltage divider inputs for Arduino and ESP32 analog pins
• Adjusting power supply outputs and reference voltages
• Speed and level controls in motor driver and dimmer circuits
• Volume and tone controls
• Test equipment and lab benches

What's in the Box

• 1 × 20 kΩ 2 W potentiometer

Tip: For a voltage divider, connect the outer pins to the supply and GND and the middle pin (wiper) to your input. When it is wired as a variable resistor, keep the current low: the power rating applies to the whole track, so a small section heats up much faster.
