Bourns 3006P 500 ohm Potentiometer

It is a high-end Bourns preset. It’s a PCB/Breadboard mountable preset known as potentiometers, trimpots, and other names, but it’s simply a variable resistor. This preset must be cranked ten times to alter the resistance from 0 to full range, providing higher precision in obtaining the needed resistor.
Three leads are coming out of it. The resistance between the outer two pins is always 500 ohm. In contrast, the resistance between the external pins and the centre pin fluctuates from 0 to 500 ohm as the potentiometer screw rotates.
This potentiometer may also be used to generate a variable voltage and as a variable resistor.Connect the outer two pins to VCC and GND to use this potentiometer as a variable resistor. The middle pin outputs a variable voltage between 0 (GND) and VCC as the potentiometer is spun.
