Frequently asked questions
How do I wire a trimmer as a variable resistor?
Connect the two outer pins to the circuit ends and use the centre pin as the wiper. Turning the screw changes the resistance between the centre pin and either outer pin.
How does the 20 kΩ version differ from the 2 kΩ version?
Only the resistance value differs. The listing gives the same power rating, mounting, pin spacing, temperature range and rotational life for both.
