Variable Resistors (Rotary Potentiometer)

Overview: Variable Resistors and Rotary Potentiometers

Our variable resistors, commonly known as potentiometers, provide smooth and precise resistance adjustment for a wide range of electronic applications. Rotary potentiometers use a rotating shaft or knob to vary resistance and are the most common form factor for user controls and tuning circuits.

Key Features

• Adjustable Resistance: Fine-tune voltage and current in circuits for calibration and control.
• Smooth Operation: Engineered for consistent, low-friction adjustments and repeatable settings.
• Multiple Tapers: Available in linear and logarithmic (audio) tapers to match application needs.
• Wide Resistance Range: Offered in several values to fit signal, load, and interface requirements.
• Durable Materials: Built to withstand repeated use and environmental stresses.
• Compact Options: Multiple form factors for tight PCB layouts and varied mounting methods.

Rotary Potentiometers: Description and Uses

Rotary potentiometers adjust resistance by turning a shaft or knob that moves a wiper across a resistive element. They are commonly used for user interface controls, audio level adjustments, tuning circuits, and sensor calibration.

Common Applications

• Audio equipment: volume, tone, and balance controls.
• Industrial control: sensor calibration and instrument tuning.
• Consumer electronics: radios, TVs, and household devices.
• Automotive: dashboard controls and lighting adjustments.
• Education and prototyping: electronics kits and DIY projects.

How to Select the Right Potentiometer

1. Determine the application: Identify the function in the circuit (volume control, calibration, user input).
2. Choose the resistance value: Pick a value that matches circuit impedance and desired range of adjustment.
3. Select the taper: Use linear taper for uniform changes, logarithmic taper for audio-level control.
4. Check size and mounting: Confirm the potentiometer fits the available space and mounting type (through-hole, surface mount, panel mount).
5. Verify power and tolerance: Ensure the power rating and tolerance meet your design requirements.
