Operating temperature
Thick film makes the electrodes very strong.
Since start of production in 1976 (first in the wold), this component has established a solid reputation as a general–
purpose chip resistor.
Design and specifications are subject to change without notice. Carefully check the specification sheet before using or
ordering it.
Item
See Table 1.
Power must be derated according to the power derating curve in
Figure 1 when ambient temperature exceeds 70
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.
