Note *1 - Maximum allowable continuous Working Voltage
for all resistors is the lower of the two values:
“Maximum Working Voltage” as specifi ed above
or the result of the following formula
Power rating (Watts) x Resistance (Ohms)
Note * - Maximum Overload Voltage for all resistors is the
lower of the two values:
“Maximum Overload Voltage” as specifi ed above
or the result of the following formula
2.5x Power rating (Watts) x Resistance (Ohms) for 5 sec.
Power Derating Curve: For operation above
70oC, power ratingmust be derated according
