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. Storage Temperature 20 15C, Humidity 60%R.H.
