Anti-Sulfuration Chip Resistors SFR Series SFR01 / 03 Series
The News
ROHM has recently announced the availability of new anti-sulfuration chip resistors optimized for applications exposed to sulfur-rich environments such as communication infrastructure, automotive systems, and industrial equipment.
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.
