Note *1
- Maximum allowable continuous Working Voltage
for all resistors is the lower of the two values:
“Maximum Working Voltage” as specified above
(or)
Power rating (Watts) x Resistance (Ohms)
Note *2
- Maximum allowable Overload voltage is 2 times the
Maximum Working Voltage (see Note *1 above) or Maximum Over-
load Voltage as specified in the table whichever is lower
