Preset Potentiometers (100Ω – 500kΩ)

Preset Potentiometers, also known as trimmer potentiometers or presets, are compact variable resistors designed for fine tuning, calibration, and adjustment of electronic circuits. Unlike panel-mounted potentiometers, preset potentiometers are intended for infrequent adjustments and are usually set during manufacturing, testing, or maintenance of electronic equipment.

These components play a critical role in achieving accurate voltage, current, and signal control in a wide range of analog and digital circuits. Their small footprint, stability, and precision make them an essential choice for PCBs, embedded systems, power supplies, and industrial electronics.

Manufactured using high-quality resistive elements and durable housings, preset potentiometers ensure consistent performance, minimal drift, and long operational life, even in demanding environments.
