Anti-vulcanization patch resistor, that is, anti-vulcanization thick film chip resistor, realizes high anti-vulcanization performance through the use of anti-vulcanization electrode structure and material. The internal terminals of the thick film resistors are made of an alloy of palladium and silver to protect them from vulcanization and failure under harsh exposure. Nanjing Nanshan provides a wide range of anti-vulcanization patch resistance products, such as universal type, high power type and electric influenza type. Vulcanization-resistant patch resistors also provide a lower resistance temperature coefficient.
Anti-vulcanization patch resistor details
In areas with high concentration of sulfur gas, such as hot spring areas and mining areas, electronic equipment such as equipment exposed to highly polluted environment of sulfur gas, including industrial control systems, sensors, instrumentation equipment, communication base stations, etc., sulfur will enter the gap between the electrode and the protective layer of the patch resistor, and combine with the silver material at the end electrode of the patch resistor to produce silver sulfide. Cause the whole patch resistor to become an insulator, which makes the electronic equipment fail and even dangerous. In order to effectively solve the problem of chip resistance failure in a serious sulfur pollution environment, anti-vulcanization resistance is essential. By changing the electrode structure of the chip resistance, adding special vulcanization resistant materials to the electrode, the anti-vulcanization resistance series products have been developed, which can greatly improve the anti-vulcanization ability of the chip resistance and extend the life of electronic equipment.
