What is the specific manifestation of the small resistance error of thin film high-precision resistors

The small resistance error of thin film high-precision resistors is specifically reflected in the following aspects:

1、 Accurate manufacturing process
Thin film high-precision resistors use advanced thin film deposition technology to achieve precise control of resistance values through precise deposition of multi-layer film layers and fine resistance tuning processes. This manufacturing process ensures that the resistance error of the resistor is minimized during the manufacturing process.

2、 Strict screening and testing
During the production process, thin film high-precision resistors undergo strict screening and testing. Manufacturers will use high-precision measuring equipment to accurately measure the resistance of resistors and select resistors with resistance errors within the specified range. This rigorous screening and testing process ensures that the resistance error of the final product meets the design requirements.

3、 High resistance stability
The resistance stability of thin film high-precision resistors is very high, which means that their resistance value remains basically unchanged during long-term use. This stability helps to reduce circuit errors caused by changes in resistance values, thereby improving the accuracy and reliability of the entire circuit.

4、 Small range of resistance error
The resistance error range of thin film high-precision resistors is usually between ± 0.01% and ± 0.1%, and even some high-precision models can control the tolerance within ± 0.005%. This extremely small range of resistance error makes thin film high-precision resistors have important applications in circuits that require precise resistance values, such as precision measurement, signal processing, analog circuits, and other fields.

5、 Adaptability to temperature and environment
The small resistance error of thin film high-precision resistors is also reflected in their adaptability to temperature and environment. Due to its low temperature coefficient, its resistance value can remain stable under different temperature conditions. At the same time, thin film high-precision resistors also have good moisture resistance, corrosion resistance, and other characteristics, which can maintain stable resistance performance in harsh environments.

In summary, the small resistance error of thin film high-precision resistors is mainly reflected in their precise manufacturing process, strict screening and testing, high resistance stability, small resistance error range, and adaptability to temperature and environment. These characteristics make thin film high-precision resistors have broad application prospects and important application value in multiple fields.
