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 which leads 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-HP series is resistant to sulfur exposure, verified in accordance with the ASTM B 809 standard.
