NH020-Series Power SIPs:

Figure 32. NH020F Power Dissipation vs. Output

Current.

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. Power Derating vs. Local Ambient

Temperature and Air Velocity

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.
