Figure 6 - Typical thermal resistance vs. flowing ambient air velocity
Note 1:
These data correspond to a single module placed on a thermally insulating board and air velocity measured
approximately 1cm above the board and 0.5cm in front of the module. The airflow is parallel to the flanges of the heat
sink (100 LFM (linear feet per minute) =0.51m/s)
