Mass production of the AH series began this year. It is offered in size range 0603/0805/1206, with a high degree of anti-sulfurated, a wide operating temperature range from -55℃ to 155℃, working voltage as high as 500V(for size 1206). YAGEO’s AH series meets the most stringent testing standards with excellent anti-sulfuration characteristics according to the ASTM test. In terms of high-voltage resistance performance, AH strictly complies with the specifications and has obtained UL safety certification, which can perform well in high-voltage applications.

Sulfur penetrates resistors through the gap between the termination and the protective layer, thus producing vulcanization of the top conductor leads to circuit open problem. To achieve anti-sulfuration capability, some in the industry use gold as the inner electrode while adding an extra burden on customers’ application costs. With YAGEO’s AH series, the sulfur issues are solved by using unique dielectric material in the inner electrode with the alteration of the resistor structure. This setup not only improves the anti-sulfuration capabilities but also saves costs.

As global pollution is a rising concern, YAGEO has been dedicated to fulfilling the increasing demand for anti-sulfur with a higher power voltage capability which is a highlight under the green power policy. We make it possible for applications under harsh environments to adopt reliable anti-sulfate resistors under extreme conditions.YAGEO Group will continue to put effort into the research and development of anti-sulfuration technology, coming up with more extension products on the heels of its successful launch of the AH series.
