The PDV20-21P-103A is a type of potentiometer commonly referred to as a slide potentiometer. These slide potentiometers are simple linear voltage dividers, and they work by having a slider contact move a resistance element up or down a track to affect resistance. By doing this, the voltage across the potentiometer can be varied.

Slide potentiometers offer a high degree of precision due to their simple, linear design. They are widely used in a variety of applications such as controlling motors, volume control circuits, audio equipment, and other electronic devices that require variable resistance.

Slide potentiometers are composed of a track, contact, and shaft. The track is made of a material such as metal or plastic that is resistant to corrosion and wear. The contact is typically a metal or plastic wheel that is connected to the shaft that the user can manipulate. The shaft is what the user physically moves to adjust the resistance of the potentiometer.

Slide potentiometers work by changing the amount of resistance in the circuit. The resistance is determined by the position of the contact on the track. When the user moves the contact up the resistance will decrease, while the resistance will increase when the contact is moved down. This causes a corresponding decrease or increase in the voltage across the potentiometer, thus adjusting the output of the device.

The PDV20-21P-103A is a low power slide potentiometer that offers a wide adjustment range. It has a sliding element with a continuous range from 0 to 10 kΩ. The unit has a 200 mA maximum current rating and a basic dielectric strength of 1.5 kVACrms.

Slide potentiometers are found in a variety of applications. They are often used in circuits that require a smooth linear variation of resistance such as volume control for audio equipment. They are also used in motor speed control circuits as well as other applications that require adjusting the voltage applied to a load or circuit element.

Overall, the PDV20-21P-103A slide potentiometer is a simple, yet effective device that can be used in a variety of applications to achieve precision control. It is a reliable and durable device ideal for any application that requires variable resistance.
