• Resistance Range: 500Ω, 1kΩ, 5kΩ, 10kΩ, 50kΩ, 100kΩ, 1MΩ (most common)

• Tolerance: ±10% to ±20%

• Power Rating: 0.1W to 2W (depending on size and application)

• Adjustment Type: Rotary, Sliding, Multiturn

• Rotation Angle: 270° (standard); 10-turn options also available

• Mounting Type: Through-hole, surface-mount, or panel-mount

• Shaft Type: Knob, flat, D-shaft, slotted (for adjustment)

• Terminal Count: 3 (for potentiometer), 2 (for rheostat)

• Operating Temperature: -55°C to +125°C (varies by model)

Applications:

• Volume and tone controls in audio devices

• LCD/LED brightness adjustment

• Sensor calibration and tuning

• Power supply regulation

• Variable speed control in motors
