Farnell offers an extensive range of potentiometers, trimmers, and related accessories, designed to deliver precise control over various electrical parameters in your applications. Our collection includes different types such as rotary, linear, and slide potentiometers, ensuring you find the right solution for your specific needs.

Trimmers are miniature potentiometers, often called trimpots, used for tuning and calibration in electronic circuits. Typically mounted on PCBs, they are adjusted with a screwdriver for setting parameters during manufacturing and maintenance.

Potentiometers are three-terminal devices that function as adjustable voltage dividers. They allow for voltage adjustments by applying voltage across two terminals and adjusting the third via a sliding contact. This enables fine-tuning within circuits.

Types of Potentiometers

Rotary: Used in audio equipment for volume control. Linear: Position sensors that measure displacement along an axis, ideal for applications needing linear movement. Slide: Faders in audio for volume and frequency control with a smooth sliding action. Digital Display: Provide digital resistance readouts for precise adjustments.

With various resistance ranges, power ratings, and adjustment options, our potentiometers and trimmers suit a wide range of applications, including audio controls, instrumentation, and calibration in industrial and consumer electronics.
