The bourns potentiometer is an imported potentiometer product. At present, Bourns potentiometers are better regulated than other common potentiometers. But for the connection of the Bourns potentiometer and the ordinary potentiometer connection method is roughly the same, if not technicians, I believe we also do not know the connection method of the Bourns potentiometer, then the following to explain how to connect the Bourns potentiometer and how to eliminate noise fault.

Wiring method of Bourns potentiometer
For the connection of bourns potentiometer, it is necessary to consider that when the potentiometer adjusts the current in the DC current, the current passes through the sliding arm of the potentiometer, and the resistance value will increase abnormally due to anodic oxidation. In general, the terminals connected with the resistance body are connected to the negative pole, and the sliding arm is connected to the positive pole. If the current passes directly through the bourns 3296 potentiometer, the anode of the potentiometer will be oxidized and the resistance of the potentiometer will be increased. Therefore, it is suggested that the positive electrode of the current should be connected to the left contact terminal of the Bourns potentiometer and the negative electrode of the current should be connected to the left contact terminal of the potentiometer.

Bourns potentiometer eliminates noise fault method
As for how to eliminate the noise fault of bourns 3296 potentiometer, the method of elimination can be used to solve the problem. The first is to check whether the internal components of the potentiometer are damaged, if the surface of the potentiometer is damaged, it will also lead to some parts of the oxidation corrosion and other problems leading to noise. The second is to check whether the terminals of the potentiometer have oxidation. When the noise is too high, it can be judged that the carbon diaphragm of the potentiometer contains impurities or excessive dust. To deal with this noise problem, pure alcohol can be dripped into the carbon diaphragm inside the potentiometer, and the continuous rotating potentiometer handle makes the brush contact slide on the carbon diaphragm, thus achieving the goal. The purpose of cleaning carbon membrane is to eliminate noise.

Notes for use of bourns potentiometer
1. With regard to potentiometers of different specifications, do not replace each other in order to avoid incompatibility between the lines, resulting in damage to potentiometers.
2. Bourns potentiometer is also divided into single-loop and multi-loop regulation, for the use of potentiometers, you should distinguish clearly, in order to avoid improper operation, resulting in potentiometer failure and other accidents.
3. To avoid the bourns 3296 potentiometer in the use process, we must pay attention to prevent some water vapor intrusion. In order to avoid the internal components of potentiometer damp, and cause some short-circuit fault.
4. In the use of potentiometers, the working current should not be overloaded, so as to avoid the resistance of potentiometers will increase, resulting in damage to potentiometers.
