LC/LW010- and LC/LW015-Series Power Modules:
Thermal Considerations
The power module operates in a variety of thermal
environments; however, sufcient cooling should be
provided to help ensure reliable operation of the unit.
Heat-dissipating components inside the unit are ther-
mally coupled to the case. Heat is removed by conduc-
tion, convection, and radiation to the surrounding
environment. Proper cooling can be veried by mea-
suring the case temperature. The case temperature
(TC) should be measured at the position indicated in
8-1363(C).b
Note: Dimensions are in millimeters and (inches). Pin locations are
for reference only.

face of the modules. The temperatures at these loca-
tions should not exceed the maximum case
temperature indicated on the derating curve. The out-
put power of the module should not exceed the rated
power for the module as listed in the Ordering Informa-
tion table.
Heat Transfer Characteristics
Increasing airow over the module enhances the heat
maximum power that can be dissipated by the module
without exceeding the maximum case temperature ver-
sus local ambient temperature (TA) for natural convec-
tion through 3.0 ms–1 (600 ft./min.).
Systems in which these power modules are used typi-
cally generate natural convection airow rates of
0.25 ms–1 (50 ft./min.) due to other heat dissipating
components in the system. Therefore, the natural con-
vection condition represents airow rates of approxi-
shown in the following example.
Example
What is the minimum airow necessary for an LW010A
operating at 48 V, an output current of 2.0 A, and a
maximum ambient temperature of 91
°C?
Solution:
Given: VI = 48 V, IO = 2.0 A (IO, max), TA = 91
°C
Determine airow (Figure 43): v = 2.0 ms–1
(400 ft./min.)
