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.
The derated values of dissipation for temperatures in excess of 70°C
shall be indicated by the following Curve.
(For Jumpers the load current shall be derated according to the Derating Curve )
