Metal oxide film resistors have the following characteristics: ①Compared with metal film resistors, metal oxide film resistors have better oxidation resistance and thermal stability. ② have excellent pulse, high frequency overload, mechanical properties are better. ③ conductive film thicker, smaller range of resistance, 1Ω-200kΩ, mainly to supplement the lack of metal film resistors low-resistance resistors. ④ temperature coefficient of resistance than the metal film. ⑤ rated power range, 1 / 8W. 5OkW. Use of metal oxide film resistors Metal oxide film resistors are widely used in power automation control equipment, some of which require long-term operation in high temperature environment, the use of general resistance will not be able to maintain its stability. In this case, a metal oxide film resistor (Metal Oxide Film Resistor) may be used. The metal oxide film (such as zinc oxide) is attached to a highly heat-conductive ceramic rod by a high-temperature combustion technique, Film car screw to make different resistance, and then spray the outer layer of non-flammable paint. It can maintain its stability at high temperatures, the resistance of the membrane load power is also higher.
