NEW Anti-Sulfuration Chip Resistors Improve Safety & Reliability


ROHM announced new anti-sulfuration chip resistors optimized for applications exposed to sulfur-rich environments such as communication infrastructure, automotive systems, and industrial equipment. The resistors offer increased safety and long-term reliability in these applications, according to the company.

Compared to conventional resistors, the SFR series significantly improves sulphuration performance by utilising a proprietary original electrode structure.

Sulfur particles are generally present in the air in various forms due to sulfur and automotive exhaust gases. In sulfurous environments these particles can be adsorbed by the silver plating used in electronic components, including on the surface of the inner and side electrodes of conventional chip resistors. Eventually this can lead to silver migration and the formation of silver sulfide, causing resistance changes and, ultimately, application failure.

ROHM claims that its proprietary original electrode structure and protective material significantly improve anti-sulfuration performance, contributing to increased safety and long-term reliability.
