Potentiometer EB1076222010 20 kΩ 500 mW linear rotary potentiometer

Linear rotary potentiometer EB1076222010 with resistance 20 kΩ and rated power 500 mW is a compact through-shaft control element intended for precise analog adjustment of voltage or signal level in electronic circuits. It provides smooth linear taper response across its rotation, reliable mechanical operation and straightforward mounting for integration into audio equipment, measurement instruments, control panels and development prototypes. The potentiometer is suitable where a stable, adjustable resistance is required for tuning, calibration or user control.

Advantages

This 20 kΩ linear rotary potentiometer delivers predictable linear change of resistance with shaft rotation and supports small-signal applications thanks to its 500 mW power rating. The device combines a low-profile rotary form factor with simple mechanical mounting and robust detents or smooth shaft options depending on the variant, allowing repeatable adjustment. Its construction supports long service life under normal operating conditions and provides stable tactile feedback for manual adjustments.

Suitable for

• Audio level control and tone adjustment in amplifiers and mixers
• Calibration and trimming in measurement instruments and test equipment
• User input knobs on control panels and consumer electronics
• Prototyping and development boards requiring variable resistance

Key specifications

• Type: linear rotary potentiometer
• Resistance: 20 kΩ (linear taper)
• Rated power: 500 mW
• Termination: through-shaft mechanical mounting (panel or PCB dependent on version)
• Rotation: single-turn, smooth linear response across sweep

How to use

Mount the potentiometer in the intended panel or circuit board location following the mechanical dimensions of the chosen variant. Connect the three terminals according to the circuit: one outer terminal to reference (ground), the other outer terminal to the input signal or supply, and the wiper (middle terminal) to the output or control node. Rotate the shaft to vary the output proportionally to shaft position; small adjustments change the resistance in a linear manner. Avoid exceeding the rated power and ensure correct wiring to prevent overheating or component damage.

Usage recommendations

For reliable operation, use this potentiometer within its rated power and environmental limits, avoid excessive mechanical force on the shaft, and, when used in audio paths, place it away from high-current or noisy power traces. When integrating into designs, verify mechanical fit and shaft coupling, and if long-term stability is required, consider a sealed or higher-durability variant.
