ST7ETA102 Potentiometers, Variable Resistors

Trimmer Potentiometers: ST7ETA102 Application Field and Working Principle

The ST7ETA102 Trimmer Potentiometer is a three-terminal adjustable constant in the middle, with the two end terminals adjustable in any direction. It is commonly used in many applications requiring low-cost resistance fine-tuning, especially in radio, TV sets, measuring instruments, and electrical appliances.

For application of the ST7ETA102 Trimmer Potentiometer, it can be used to adjust the volume, frequency and phase reproduction of electronic devices, or as a low-frequency signal level signal generator. It can also be used as a signal voltage regulator or to perform certain self-test functions in various measuring instruments.A Trimmer Potentiometer\'s working principle is quite simple: By increasing or decreasing the value of the resistance by adjusting the wiper terminator, the resulting current will change accordingly. A Trimmer Potentiometer typically comes with a miniature resistance adjustment, a high gear accuracy and a good switching resistance for fine tuning. For the ST7ETA102 Trimmer Potentiometer, its size is 1.5mm×1.5mm and the resistance value range is 1K ohm to 10K ohm.

In sum, a Trimmer Potentiometer, such as the ST7ETA102 Trimmer Potentiometer, is a miniature, low-cost, high-precision device that provides a series of resistances for various applications. It features a wide resistance range, small size, and high accuracy, making it perfect for adjusting the volume, frequency, and phase reproduction of a variety of electronic devices.
