Note that the natural convection condition was
measured at 0.05 m/s to 0.1 m/s (10ft./min. to 20
ft./min.); however, systems in which these power
modules may be used typically generate natural
convection airflow rates of 0.3 m/s (60 ft./min.) due to
other heat dissipating components in the system. The
use of Figures 53 - 59 are shown in the following
example:
Example
What is the minimum airflow necessary for a
JRW060A0F operating at VI = 48 V, an output current
of 42A, and a maximum ambient temperature of 70 °C
in transverse orientation.
Solution:
Given: VI = 48V
Io = 48A
T
Determine airflow (V) (Use Figure 53):
V = 1m/sec. (200ft./min.)

(Vo = 12V) in Transverse Orientation with no
baseplate; Airflow Direction From Vin(+) to Vin (-);
Vin = 48V.
Figure 54. Output Power Derating for JRW040A0A
(Vo = 5V) in Transverse Orientation with no
baseplate; Airflow Direction From Vin(+) to Vin (-);
Vin = 48V.
