Ruthenium oxide dielectric offers superior resistance to the elements.
3) Electrodes not corroded by soldering
Thick film makes the electrodes very strong.
4) Leading the world in development and mass production.
Since start of production in 1982 (first in the wold), this component has established a solid reputation as a general–
purpose chip resistor.
5) ROHM resistors have approved ISO–9001 certification.
Design and specifications are subject to change without notice. Carefully check the specification sheet before using or
ordering it.

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.

!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.
