Potentiometer 2W 5K ohm

The Potentiometer 2W 5K ohm is a rotary variable resistor with a total resistance of 5 kΩ and a power rating of 2 W. Turning the shaft moves the wiper along the track to give an adjustable resistance, or an adjustable voltage from the centre pin. The 5 kΩ value works well as a control knob for Arduino and ESP32 analog inputs and for adjusting voltage regulators, op-amps and timers.

Potentiometer 2W 5K ohm Specifications

• Resistance: 5 kΩ across the full track
• Power rating: 2 W
• Type: rotary potentiometer, 3 terminals
• Wiring: two track ends plus the centre wiper
• Current through the full track: 1 mA at 5 V, 2.4 mA at 12 V
• Pack size: 1 piece

Potentiometer 2W 5K ohm Applications

• Analog control knobs for Arduino and ESP32 projects
• Setting the output voltage of adjustable regulators such as the LM317
• Op-amp gain, offset and comparator threshold adjustment
• Speed and brightness control knobs read by a microcontroller
• Repairs and electronics lab work

What's in the Box

• 1 × 5 kΩ 2 W potentiometer

Tip: Connect the outer pins to 5 V (or 3.3 V) and GND and the centre pin to an analog input to read the knob position. The 2 W rating applies to the whole track; if you use only two pins as a variable resistor, a smaller part of the track carries the current, so keep it well below the full-track limit of about 20 mA.
