This specification is available for Wirewound Resistor manufactured by Jackcon (HK) Industrial Limited ,it accords with RoHS test of Environment related substance requirement.


Application


Ideal for pulse application


Specification


1.Rated Power


Rated power is maximum power which can be continuously loaded at specified ambient temperature

70℃,as Table-1;however when the ambient temperature exceeds 70℃,rated power should be determined

from the derating curve of Fig.1.
