Dial Wheel Potentiometer PCB Mount Assortment Kit — Multiple Values & Tapers

Dial Wheel Potentiometer PCB Mount Assortment Kit — Multiple Values & Tapers

A comprehensive dial wheel potentiometer PCB mount assortment kit including multiple resistance values from 1KΩ to 500KΩ in both linear (B) and audio (A) tapers. Dial wheel potentiometers feature a thumbwheel adjustment mechanism that can be turned with a finger without a screwdriver — ideal for panel-accessible fine adjustment controls on PCBs. The PCB-mount format solders directly to the board for a compact, integrated control.

Linear vs Audio Taper

• Linear (B): Resistance changes proportionally with rotation — for sensor and voltage divider applications
• Audio (A): Logarithmic response — matches human hearing perception for volume controls

Typical Applications

• Arduino analog input adjustment potentiometer
• Volume and tone control for audio circuits
• Bias and offset adjustment on PCBs
• Sensor sensitivity adjustment
• LED brightness fine-tuning control
