Rated ambient temperature: + 70° C
Operating temperature range: - 55° C ... + 125° C
Preferred
* For resistors operated at an ambient temperature of +70°C or above, the power rating shall be derated.
Power rating depends on resistance value.
Performance requirements are dependant on the power rating.
Please consult with us for power rating before you order and use.
Rated voltage = Power rating x resistance value or max. working voltage, whichever is lower.
*** Resistance values for T.C.R. ±100 ppm/K are E24 series only.
*** T.C.R. ±5ppm/K is guaranteed in the temperature range +25°C…+125°C.
