Resistance value is marked on the top surface.
The rated voltage shall be determined by the following expression.
-55℃ to +125℃
Note * :
Power rating is based on continuous full load operation at rated ambient temperature of 70℃.
For resistors operated at ambient temperature in excess of 70℃, the maximum load shall be
derated in accordance with the following curve.
