TRR Series Sulfur Tolerant Chip Resistors


Anti-sulfur chip resistors feature a unique internal structure


ROHM's TRR SeriesConventional 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.

The TRR series from ROHM features an operating temperature range of -55°C to +155°C. Accelerated testing shows the lifetime of the TRR series will exceed 90 years. This product is suitable for high-reliability applications and circuits, including Industrial, Automotive, Metering, and other outdoor sulfur-rich environments.

Features
  • Unique protection materials prevent formation of silver sulfide in sulfur-rich environments
  • Highly recommended for automotive, industrial and power supply applications in sulfur-rich environments
  • Have good cost performance unlike the Au terminal components from other suppliers
  • ROHM resistors have been approved to the ISO9001/ISO/TS 16949 certification
