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 produc-
tion.
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 certifica-
tion.
Design and specifications are subject to change with-
out notice. Carefully check the specification sheet be-
fore using or ordering it.

Rated voltage
The voltage rating is calculated by the following equation. If the value
obtained exceeds the maximum operating 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.
