Trimmer Potentiometers

Trimmer potentiometers are small, adjustable resistors used to fine-tune electrical circuits. They have a rotating shaft with a resistance element that can be turned to change the resistance value, allowing for precise adjustments to be made to circuit parameters such as voltage, current, or frequency. Commonly used in audio equipment, radio transmitters, and medical devices, trimmer potentiometers are available in various sizes, shapes, and materials, including linear, logarithmic, and digital types. They offer reliable, stable performance and are often used in applications where precise control is essential.
