Resistance of metal oxide film

Metal oxide film resistance is currently widely used in power automation master buildings, some instruments or assembly requirements are always operating in a high temperature environment, the use of ordinary resistance will not be connected to its stability. In this environment can be used metal oxide film resistance (metal oxide film resistor), it is the use of high temperature incineration technology on the high heat conduction of porcelain rod burning a layer of metal oxide film (such as zinc oxide) on the metal oxide film car helical to make a difference in resistance, and then on the outer coating of non-combustible coating. It may be able to maintain its stability at high temperatures, resistance film load power is also high.
