Trimming Potentiometers for Precision Adjustment – SMD, Wirewound, and Multi-Turn Types
TL;DR: Trimming potentiometers provide precise resistance adjustment for calibration, signal tuning, and voltage control in LCD modules, set-top boxes, instruments, and communication devices.
What Is a Trimming Potentiometer?
A trimming potentiometer is a variable resistor used for fine adjustment of voltage, current, or signal levels during circuit calibration. It enables precise tuning in analog and digital electronics and is commonly used in factory calibration and field adjustment.
