product description:
A metal film resistor is a resistor that forms a resistive film layer on a ceramic or glass substrate by using a special metal or alloy as a resistive material by vacuum evaporation or sputtering. Such 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.
