Frequently asked questions
Is it suitable for power circuits?
No. It is a low-power trimmer rated at 1/2 W, so it should only be used in signal and low-current circuits, not to carry load current.
How do I wire it as a variable resistor?
Connect one outer pin and the centre pin (wiper) across the two points you want to vary. Using all three pins as a divider is also possible if you need a variable voltage.
