Trimmer Potentiometer 20K Ohm

The Trimmer Potentiometer 20K Ohm is a small preset variable resistor with a total resistance of 20 kΩ. Trimmers are adjusted with a small screwdriver and then left in place, which makes them ideal for calibration and fine tuning on a PCB or breadboard, such as setting sensor thresholds, timer periods or amplifier gain.

Trimmer Potentiometer 20K Ohm Applications

• Calibrating sensor thresholds and comparators
• Setting the frequency or delay of 555 timer circuits
• Setting op-amp gain and offset
• Fine-tuning voltage dividers and reference voltages
• LCD contrast adjustment
• Electronics education and prototyping

What's in the Box

• 1 × 20 kΩ trimmer potentiometer

Tip: Connect the outer pins across the supply and the middle wiper pin to the circuit, or use the wiper and one outer pin as a variable resistor. Turn it gently with a screwdriver that fits the slot, as trimmers are not made for frequent adjustment.
