A Single Gang Linear Potentiometer (B100K Rotary Variable Resistor) is a 3-terminal manually adjustable resistor designed to control voltage levels, sensor references, and signal conditioning circuits. Constructed with an internal carbon track and a rotating wiper contact attached to a slotted metal shaft, rotating the shaft changes resistance continuously between the wiper and outer terminals. Marked with a "B" prefix, it features a linear taper that delivers a uniform, proportional resistance adjustment relative to shaft rotation.

This product is featured by Famephase Electronic Accessories as an essential variable control component for volume adjustments, brightness control, variable power supply tuning, and microcontroller analog input signals.
