For a better life cycle under normal usage, 50% of the rated power is recommended
* Rated Continuous Maximum Working Voltage (RCWV) should be determined from RCWV =√Power Rating x Resistance Values Max. RCWV listed above.
** Short-time Overload (STOL) test should be determined from STOL=√2.5 x Power Rating x Resistance Values or maximum overload voltage listed above, whichever is lower.
