Yageo’s range of anti-sulfurated resistors are designed for use in environments exposed to high levels of contamination, which could include industrial control systems, sensors and wireless basestations.
Anti-sulfurated resistors currently only occupy a small proportion of the overall resistor market, but according to Yageo as environmental pollution is a rising concern, there has been an increasing demand by terminal equipment manufacturers for anti-sulfuration features in the past two years.
“We have received a steady stream of customer inquiries, which led to more focus on anti-sulfurated resistor research and development,” said the company.
In contrast to industrial electric instrumentation and base station equipment, most consumer electronic products don’t have anti-sulfuration requirements. However, certain atmospheric conditions release substances causing sulfuration reaction which further affects the efficiency of electronic products.
This makes it necessary for some electronic product manufacturers to use anti-sulfate resistors under extreme environmental condition.
