Preset Potentiometers

Trimmer potentiometers are small potentiometers that allow for very fine adjustments to be easily made to a circuit, and are often called trim pots. Single turn rotary preset potentiometers are miniature versions of the standard variable resistor designed to be mounting directly on a printed circuit board (PCB) and are adjusted by means of a small bladed screwdriver or similar plastic tool. They can be either horizontal or vertical mounting.
