TRR01 Resistors Sulfur Tolerant Chip Resistors TRR01 (0402 size) z Features 1) Unique protect materials prevent from silver sulfide occurrence under sulfur enviromnet. 2) Highly recommended for automotive, industrial and Power supply applications under sulfur environment. 3) Realize the good cost performance not like the Au terminal components. 4) ROHM resistors have approved ISO9001 / ISO/TS 16949 certification. Design and specifications are subject to change without notice. Carefully check the specification sheet supplied with the product before using or ordering it. z Ratings Item Conditions Specifications 0.063W (1 / 16W) Power must be derated according to the power derating curve in Rated power Figure 1 when ambient temperature exceeds 70C. at 70C 100 80 60 40 20 0 55 0 70 100 155 AMBIENT TEMPERATURE (C) Fig.1 Rated voltage The voltage rating is calculated by the following equation. If the value obtained exceeds the limiting element voltage, the voltage rating is equal to the maximum operating voltage.
