Potentiometer 2W 5M ohm

The Potentiometer 2W 5M ohm is a variable resistor with a 5 MΩ track and a 2 W power rating. Adjusting the control moves a wiper along the track, letting you vary the resistance or set any voltage between the two ends. The high 5 MΩ value is meant for high-impedance and low-current circuits, and the 2 W rating leaves a generous safety margin on power.

Potentiometer 2W 5M ohm Specifications

• Type: potentiometer (variable resistor)
• Resistance: 5 MΩ (5,000,000 ohms) end to end
• Power rating: 2 W
• Connections: two track ends and a wiper
• Track current at 5 V: about 1 µA

Potentiometer 2W 5M ohm Applications

• Adjustment in high-impedance amplifier and sensor circuits
• Long RC time delays in timer circuits such as the NE555
• Very low-current voltage dividers and bias networks
• Replacing a worn potentiometer of the same value in repairs
• Electronics labs and experiments

What's in the Box

• 1 × 2 W potentiometer, 5 MΩ

Tip: The 2 W rating applies when the whole track carries the current. When you use it as a variable resistor with only part of the track in circuit, keep the current through the wiper below the full-track value, about 0.63 mA for 5 MΩ at 2 W (I = √(P / R)).
