Applications
Ruthenium oxide dielectric offers superior resistance to the elements.
Design and specifications are subject to change without notice. Carefully check the specification sheet before using or
ordering it.
Item
Power must be derated according to the power derating curve in
Figure 1 when ambient temperature exceeds 70° C .
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.
See Table 1.
