The electronics industry has observed an increase in the incidents of corrosion failures related to high sulfur-containing environments, revealing the presence of Silver-Sulfide growth, leading designers toward sulfur resistant resistors. With sulfur resistant design construction along with a specialized design safeguarding for optimal coverage of the interface region of the product termination and coating, the RCA series is resistant to sulfur exposure, verified in accordance with ASTM B809-95 standard and EIA-977 standard.
