*1: Use it on the condition that the case temperature is below the upper category temperature.
*2: Rated Continuous Working Voltage (RCWV) shall be determined from RCWV=√Power Rating × Resistance Values,
or Limiting Element Voltage listed above, whichever less.
*3: Overload Test Voltage (OTV) shall be determined from OTV=Specified Magnification (2.5) × RCWV or Maximum Overload
Voltage listed above, whichever less.
*4: E192 series resistance values are also available. The E192 series has custom part numbers. Please contact us for details.
*5: Expanded resistance range
Power derating curve
For resistors operated in ambient temperatures
above 85℃, power rating shall be derated in
accordance with the figure on the right.
