10k Ohm Trimmer Potentiometer (3386 Package)

A fixed resistor sets one value and stays there, but plenty of circuits need a bit of fine-tuning after assembly, whether that's dialing in exact LED brightness, calibrating a sensor's output threshold, or trimming an oscillator's frequency to spec. This 3386-package trimmer potentiometer gives a project that adjustment in a 10k ohm range, small enough to tuck onto a PCB and adjust with a small screwdriver rather than needing a panel-mounted knob. It is a standard calibration component across countless hobby and semi-professional circuit designs that need a one-time or occasional fine adjustment point.
