The TRR01 0402 1/4 Sulfur Tolerant Chip Resistors is a new product from ROHM. It features a unique protective material that prevents silver sulfide from occurring under sulfur environments, and it is highly recommended for applications in automotive, industrial, and power supply applications under sulfur environments. It also has good cost performance compared to Au terminal components.
The TRRO01 series are sulfur‑tolerant chip resistors designed for automotive, industrial and power‑supply applications where exposure to sulfur can cause silver sulfide formation. They are built with a silver thick‑film electrode and a protective coating to ensure reliability in harsh environments.
