Frequently asked questions
Is this a trimmer or a regular potentiometer?
It is a trimmer for occasional adjustment during setup, not for frequent user control. Its rated rotational life is 200 cycles, so it suits calibration rather than a front-panel knob.
How do I wire it as a variable resistor?
Connect one outer pin and the centre pin to the circuit, which gives a variable resistance between them. To use it as a voltage divider, connect the two outer pins across the supply and take the output from the centre pin.
