The 1K preset potentiometer is a compact, PCB-mountable variable resistor featuring three terminal pins. The output voltage between its terminals changes as the adjustment screw is rotated using a screwdriver. It is designed for precise tuning and calibration in electronic circuits, making it convenient to install and adjust directly on a PCB.
Preset potentiometers are commonly used in electronic circuits where fine adjustments are required during manufacturing, calibration, or maintenance. These variable resistors help regulate and fine-tune voltage levels according to circuit requirements, ensuring optimal performance.
