KOA Speer Sulfuration of Resistors Technical Note
KOA Speer provides solutions for sulfuration in flat chip resistors, particularly thick film types. Sulfuration occurs when resistors are exposed to sulfur, forming silver sulfide in internal electrodes, leading to conductivity loss and open circuits. KOA Speer addresses this with specialized resistors using non-sulfurating materials and protective layers, ensuring reliable performance in sulfur-rich environments.
