An input line fuse must always be used. This encapsulated power module can be used in a wide variety of applications, ranging from simple stand-alone operation to an integrated part of a sophisticated power architecture. To preserve maximum flexibility, internal fusing is not included however, to achieve maximum safety and system protection, always use an input line fuse. The safety agencies require a normal-blow fuse with a maximum rating of 15 A see Safety Considerations section . Based on the information provided in this data sheet on inrush energy and maximum dc input current, the same type of fuse with a lower rating can be used. Refer to the fuse manufacturer’s data for further information. Tyco Electronics Corp. The temperature at this location should not exceed 100 °C. The output power of the module should not exceed the rated power for the module as listed in the Ordering Information table. Although the maximum case temperature of the power modules is 100 °C, you can limit this temperature to a lower value for extremely high reliability. Heat Transfer Without Heat Sinks Increasing airflow over the module enhances the heat transfer via convection. Figure 21 shows the maximum power that can be dissipated by the module without exceeding the maximum case temperature versus local ambient temperature TA for natural convection through 4 m/s 800 ft./min. . Note that the natural convection condition was measured at m/s to m/s 10 ft./min. to 20 ft./min. however, systems in which these power modules may be used typically generate natural convection airflow rates of m/s 60 ft./min. due to other heat dissipating components in the system.
