Trimmer Potentiometers

Trimmer potentiometers, also known as preset potentiometers, are regulatable resistors that can be adjusted to a certain value precisely and repeatedly. The 72RXWR1KLF is one of the trimmer potentiometers in the industry. This article will discuss its application field and working principle.

Application field of 72RXWR1KLF

The 72RXWR1KLF series is mainly used for volume control in amplifier circuits which is designed for the telecom industry. This series also offers excellent linearity, low and consistent temperature stability, low distortion, and reduced noise in portable audio applications. It also can be used in consumer electronics such as CD players, and home theater systems.

Working principle of 72RXWR1KLF

The 72RXWR1KLF series is basically a variable resistor or potentiometer. It is an electronically adjustable device, which means that the resistance is adjustable with the help of an electrically powered device, such as a microcontroller.The 72RXWR1KLF series consists of a resistive element which has three terminals and usually has a rotary shaft which can move along a circuit board to adjust the resistance. When the shaft is turned to the right, the resistance increases, and when the shaft is turned to the left, the resistance decreases.The 72RXWR1KLF has a linear resistor network, which means that the resistance is linearly proportional to the angle of rotation. This means that the resistance changes in the same way as the rotary shaft is moved. This makes it easy to adjust the resistance precisely.

Conclusion

The 72RXWR1KLF series is a trimmer potentiometer which is mainly used for volume control in amplifier circuits designed for the telecom industry. It features excellent linearity, low and consistent temperature stability, low distortion, and reduced noise. The 72RXWR1KLF has a linear resistor network, which means that the resistance is linearly proportional to the angle of rotation, and this makes it easy to precisely adjust the resistance.
