Trimmer Potentiometer 50K Ohm (5pcs)

The Trimmer Potentiometer 50K Ohm pack contains five small adjustable resistors with a total resistance of 50 kΩ each. A trimmer is set with a small screwdriver and then left in place, so it is used to calibrate and fine-tune circuits rather than as an everyday control knob. Typical uses include sensor calibration, setting reference voltages and adjusting gain on circuit boards.

Trimmer Potentiometer 50K Ohm Applications

• Calibrating sensor modules and analog inputs
• Setting threshold levels on comparators such as the LM339 and LM393
• Adjusting the output voltage of LM317 regulator circuits
• Fine-tuning op-amp gain and offset
• Timing adjustment in NE555 circuits

What's in the Box

• 5 × 50 kΩ trimmer potentiometers

Tip: Use a screwdriver that fits the slot well and turn gently, as small trimmers are not designed for frequent adjustment. Measure between the wiper and one end with a multimeter while adjusting to set an exact value.
