(1) Rated Continuous Working Voltage (RCWV) shall be determined from RCWV=√Rated Power

× Resistance Values, or Limiting Element Voltage

listed above, whichever less.

(2) Overload (Short-time Overload) Test Voltage (SOTV) shall be determined from SOTV=2.5

× Power Rating or max. Overload Voltage listed above

whichever less.

(3) E192 series resistance values are also available. Please contact us for details.

Power Derating Curve

For resistors operated in ambient temperatures above

85 °C, power rating shall be derated in accordance

with the figure on the right.
