Trimmer Potentiometers and their Application Field and Working PrincipleTrimmer Potentiometers are widely used in a variety of electronic circuits and devices. They are small, discrete components that can be used to precisely adjust the resistance of an electronic circuit. The most common type is the 72PMR100KLF, also known as a rotary trimmer potentiometer. A 72PMR100KLF consists of a three-terminal device that can easily be adjusted manually by rotating its shaft. A single annular track, made of a continuous-film metallic potentiometer is formed on the outside surface of the device. The shaft contains a wiper contact, which makes contact with the track and adjusts the resistance. The wiper contact is connected to one of the three external terminals, and the other two terminals are connected to the ends of the potentiometer track. The resistance is adjusted by rotating the shaft, which moves the wiper contact along the potentiometer track. The application field for the 72PMR100KLF is quite extensive, and it is commonly used as a variable resistor in consumer electronics, including audio systems, radios, remote controls, and other applications. The 72PMR100KLF can also be used as a tuner, allowing an adjustment of the frequency of a circuit by varying the resistance of the device.In addition, the 72PMR100KLF is often used to precisely adjust the gain of a circuit. This is a common use for audio systems, where the gain needs to be precisely adjusted. The 72PMR100KLF is also advantageous in this application, since it can be easily adjusted manually, without the need for external sources. Finally, the 72PMR100KLF can also be used in instrumentation systems to measure electrical signals.In terms of its working principle, the 72PMR100KLF follows a very simple concept. The device provides a variable resistance that is adjusted by rotating its shaft. As the shaft is rotated, the wiper contact slides along the potentiometer track, adjusting the resistance accordingly. The 72PMR100KLF can be adjusted to provide any type of resistance within its range.The 72PMR100KLF is an ideal trimmer potentiometer for a variety of applications. Its simple operation and adjustable resistance make it a popular choice for electronics engineers. Furthermore, its small size and discrete design make it an ideal choice for use in consumer electronics devices.
