Note1. Rated Voltage = (Rated Dissipation)×(Rated Resistance). (d.c. or a.c. r.m.s. Voltage)
Note2. Limiting Element Voltage can only be applied to resistors when the resistance value is equal to or higher than the critical resistance value.
Note3. Critical Resistance Value is the resistance value at which the rated voltage is equal to the limiting element voltage.
•Derating Curve
The derated values of dissipation for temperatures in excess of
70°C shall be indicated by the following Curve.
