High-precision resistors are widely used in high-precision circuits used for precision measurement, measuring systems, precision instruments, and other applications. Some examples of application areas for high-precision resistors include:

1. Electronic measuring instruments and testing equipment, such as multimeters, oscilloscopes, spectrum analyzers, and so on.

2. Control systems and automation, such as industrial automation, motor control, robot control, etc.

3. Signal processing and transmission systems, such as signal amplification, filtering, and registration in audio, video, and communication fields.

4. Medical diagnostic equipment, such as digital X-rays, magnetic resonance imaging (MRI), electrocardiographs, etc.

5. Scientific experimental instruments, such as precision measurement, optical and particle physics experiments, etc.

6. Aerospace and defense, such as navigation, satellite communication, radar, flight control, etc.

Overall, high-precision resistors are applied in areas that require high-precision measurements and control.
