Potentiometer Carbon 2.2K ohm

The Potentiometer Carbon 2.2K ohm is a carbon-track potentiometer with a resistance of 2.2 kΩ. Adjusting the control moves a wiper along the carbon track, so you can vary the resistance or pick off any voltage between the two ends. The low 2.2 kΩ value gives a stable, low-impedance output that reads cleanly on Arduino and ESP32 analog inputs.

Potentiometer Carbon 2.2K ohm Specifications

• Type: carbon-track potentiometer (variable resistor)
• Resistance: 2.2 kΩ (2,200 ohms) end to end
• Connections: two track ends and a wiper
• Use: voltage divider or variable resistor (rheostat)
• Track current at 5 V: about 2.3 mA

Potentiometer Carbon 2.2K ohm Applications

• Analog control input for Arduino and ESP32 projects
• Adjustable reference voltages for comparators and op-amps
• Setting levels and thresholds in test circuits
• Replacing a worn potentiometer of the same value in repairs
• Electronics classes and STEM projects

What's in the Box

• 1 × carbon potentiometer, 2.2 kΩ

Tip: Connect the two end pins to 5 V (or 3.3 V) and GND and the wiper (usually the middle pin) to an analog input; an Arduino Uno then reads 0 to 1023 across the range. At 5 V the track draws about 2.3 mA continuously.

Orders placed before 14:00 are ready for pickup the same day. Delivery across Lebanon usually takes 1–3 working days.
