Frequently asked questions
How do I wire it in a circuit?
Connect the two outer terminals across the supply or reference, and take the output from the centre wiper pin. Turning the adjustment changes the voltage at the wiper.
Is it suitable for a frequently used volume control?
It is a trimmer meant for occasional setting. For frequent manual adjustment, a panel-mount potentiometer with a knob is usually more practical.
