Product Description
Potentiometers usually consist of a resistor body and a movable brush.
When the brush moves along the resistor body, the resistance value or voltage that has a certain relationship with the displacement is obtained at the output end.
Potentiometers can be used as both three-terminal components and two-terminal components.
Because its function in the circuit is to obtain an output voltage that has a certain relationship with the input voltage (applied voltage), it is called a potentiometer.
1. Used as a voltage divider
The potentiometer is a continuously adjustable resistor. When the handle or slide of the potentiometer is adjusted, the movable contact slides on the resistor body.
⒉. Used as a varistor
When the potentiometer is used as a varistor, it should be connected as a two-terminal device to obtain a smooth and continuously changing resistance value.
3. Used as a current controller
When the potentiometer is used as a current controller, one of the selected current outputs must be a sliding contact terminal.
Installation method: Insert the lead end of the potentiometer into the hole of the printed board, and tighten it
paste, fix with solder
