TEMPERATURE DERATING
The derating graphs are based on the following airflow conditions, for a component mounted on a 25mm x 25mm copper covered pcb and are provided for information
only. Actual performance in an application is likely to differ from these results, and a customer should evaluate the thermal environment the NXJ1 is used in, to achieve a
recommended maximum component surface temperature of 85°C for the NXJ1S0303SC or 105°C for all other variants.
