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 from other suppliers.
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

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.

Before using components in circuits where they will be exposed to transients such as pulse loads (short–duration, high– level loads), be certain to evaluate the
component in the mounted state. In addition, the reliability and performance of this component cannot be guaranteed if it is used with a steady state voltage that
is greater than its rated voltage.
