Trimmer Potentiometers - 91BR2MEGLF Application Field and Working Principle

Trimmer potentiometers, also known as trim pots, are three-terminal variable resistors that offer a user-adjustable resistance at a termination point on a printed circuit board, and they are widely used in controlling electrical signals in many applications. The 91BR2MEGLF is a popular Trimmer Potentiometer and is typically used to adjust power conversion, AC line voltage, and gain circuits.

Application Field of 91BR2MEGLF

Specifically, the 91BR2MEGLF is primarily used for regulating the output voltage of AC-DC converters. The 91BR2MEGLF adjusts the output voltage of AC-DC converters to match the secondary voltage level of consumer devices. It is also used to adjust gain circuits in audio amplifiers and other power circuits, as well as controlling the gain in line amplifiers.

Working Principle of 91BR2MEGLF

As mentioned above, the 91BR2MEGLF is a three-terminal variable resistor. Each terminal is connected to a different resistance element. The center terminal is the changing resistance terminal, and the other two outer terminals are the positive and negative voltage terminals. When a voltage is applied to the input voltage terminals, the output voltage will change in accordance with the resistance value of the center terminal. When the resistance value of the center terminal is increased, the output voltage will be lower, and when the resistance value of the center terminal is decreased, the output voltage will be higher.

The 91BR2MEGLF is a non-latching potentiometer. This means that the output voltage level will not be saved when the device is not receiving a voltage. It must be adjusted every time it is powered up and receive a voltage signal or it will not work properly. The 91BR2MEGLF can be used for many other applications as well such as adjusting gain circuits in audio amplifiers and line amplifiers as well.

Conclusion

The 91BR2MEGLF is a popular Trimmer Potentiometer that can be used for a variety of applications. It is mainly used to regulate the output voltage of AC-DC converters, adjust gain circuits, and control the gain in line amplifiers. The 91BR2MEGLF is a three-terminal variable resistor and is non-latching potentiometer. This means that it must be adjusted every time it receives a voltage signal or it will not work properly. Thanks to its versatility and easy to use nature, the 91BR2MEGLF is a must-have component for application engineers.
