Conventional resistors are susceptible to sulfur penetration, causing silver migration from the terminals, which can lead to failure. ROHM's TRR series of chip resistors utilizes a special structure especially designed to prevent sulfur penetration, eliminating failures due to silver sulfide. ROHM's anti-sulfur chip resistors feature a unique internal structure that offers high tolerance to sulfuric environments. Cost is controlled by ROHM through the use of common materials such as silver (Ag), nickel (Ni), and tin (Sn), while eliminating gold (Au) - which is often used in other sulfur tolerant chip resistors.
