Figure 32. NH020F Power Dissipation vs. Output
With the known heat dissipation and a given local ambient
temperature, the minimum airflow can be chosen from the
derating curves in Figure 33.
Figure 33.
For example, if the unit dissipates 2.0 W of heat, the mini-
mum airflow in an 80 °C environment is 1.0 m/s
(200 ft./min.).
Keep in mind that these derating curves are approximations
of the ambient temperatures and airflows required to keep
the power SIP temperature below its maximum rating. Once
the SIP is assembled in the actual system, the SIP’s temper-
ature should be checked as shown in Figure 28 to ensure it
does not exceed 115 °C.
Layout Considerations
Copper paths must not be routed between pins 2 and 3 and
pins 7 and 8.
