Thumbwheel Potentiometers

Category Introduction

Thumbwheel potentiometers allow for manual adjustment of an in-circuit resistance value. Also known as thumbwheel trim pots, they are available in side or top adjustment and include a tactile edge on the actuator for human interaction and position indication. They range in value from 10Ω to 5MΩ of resistance and 5% to 30% of value tolerance in surface and through hole mounting configurations.
