Ratings
(1) Rated Continuous Working Voltage (RCWV) shall be de ter mined from RCWV=
√
Rated Power × Re sis tance Values, or Limiting Element Voltage
list ed above, whichever less.
(2) Overload (Short-time Overload) Test Voltage (SOTV) shall be de termined from SOTV=2.5 × RCWV or max. Over load Volt age list ed above which ev er less.
(3) E192 series resistance values are also available. Please contact us for details.
(4) Duplicated resistance values between E96, E192 and E24 series shall follow E24 Part Numbers. (apply three digit resistance value)
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.
