Thermal Considerations
The JW030-Series Power Modules are designed to operate in a variety of thermal environments. As with any elec-
tronic component, sufficient cooling must be provided to help ensure reliable operation. Heat-dissipating compo-
nents inside the module are thermally coupled to the case to enable heat removal by conduction, convection, and
radiation to the surrounding environment.
The thermal data presented is based on measurements taken in a wind tunnel. The test setup shown in Figure 27
was used to collect data for Figure 34.
The graphs in Figures 28 through 33 provide general guidelines for use. Actual performance can vary depending
on the particular application environment. The maximum case temperature of 100 °C must not be exceeded.
Note: Dimensions are in millimeters and (inches).
Basic Thermal Performance
The JW030-Series Power Modules are constructed with a specially designed, heat spreading enclosure. As a
result, full-load operation in natural convection at 50 °C can be achieved without the use of an external heat sink.
Higher ambient temperatures can be sustained by increasing the airflow or by adding a heat sink. As stated, this
data is based on a maximum case temperature of 100 °C and measured in the test configuration shown in
Figure 27.
