Potentiometer 2W 1K ohm

The Potentiometer 2W 1K ohm is a rotary variable resistor with a total resistance of 1 kΩ and a power rating of 2 W. The higher power rating lets it handle more current than standard small potentiometers, so it suits adjusting voltage regulators, setting bias and current in power circuits, and building simple variable test loads.

Potentiometer 2W 1K ohm Specifications

• Resistance: 1 kΩ across the full track
• Power rating: 2 W
• Type: rotary potentiometer, 3 terminals
• Wiring: two track ends plus the centre wiper
• Maximum current through the full track: about 45 mA (from P = I² × R)
• Pack size: 1 piece

Potentiometer 2W 1K ohm Applications

• Adjusting the output voltage of LM317 and similar regulators
• Setting current or brightness in LED and lamp circuits
• Variable voltage dividers and reference voltages
• Simple variable loads for testing
• Repairs of amplifiers and power equipment

What's in the Box

• 1 × 1 kΩ 2 W potentiometer

Tip: The 2 W rating applies to the whole track. When you use the potentiometer as a variable resistor (rheostat) with only part of the track in circuit, the allowed power drops in proportion, so keep the current below about 45 mA in every position.
