Trimmer potentiometers allow for precise manual adjustment of an in-circuit resistance value. Also known as trimpots, they are available in bottom, side or top adjustment and may allow for single or multiple turns of actuation. They range in value from 10 Ω to 5 MΩ of resistance and 5% to 30% of value tolerance in surface mount, through-hole, chassis mount, and panel mount configurations.
