Performance Characteristics of Metal Film Resistors Metal film resistors are generally produced by a vacuum evaporation process in which the alloy is heated in a vacuum and the alloy is evaporated to form a conductive metal film on the surface of the ceramic rod. The groove can be changed by changing the thickness of the metal film.

Its heat resistance, noise potential, temperature coefficient, voltage coefficient and other electrical properties are superior to carbon film resistors. The manufacturing process of the metal film resistor is relatively flexible, and not only the material composition and the film thickness thereof can be adjusted, but also the resistance can be adjusted by the groove, so that a resistor having a good performance and a wide resistance range can be obtained.

Development trend of metal film resistors

1. Miniaturization and high reliability;

2. Discrete small metal film resistors are still widely used, but will further reduce the size, improve performance and lower the price;

3. In consumer electronic products, carbon film resistors still dominate, while precision resistors will be dominated by metal film resistors;

4. In order to adapt to the development of circuit integration and planarization, the need for chip resistors will increase significantly; the general type will tend to develop thick film resistors, while the precision type will still tend to the metal film in the film type and Metal foil resistor

5. Develop a combined resistance network.
