Heat is removed by conduction, convection, and radiation to the surrounding environment. The thermal data presented is based on measurements taken in a set-up as shown in fig 1. when the airflow is parallel to the long axis of the module. The de-rating applies accordingly. The temperature at either location should not exceed 110 C. The output power of the module should not exceed the rated power for the module (VO, set x IO, max). Figure 1: Thermal Measurement Setup Convection Requirements for Cooling To predict the approximate cooling needed for the module, refer to the Power Derating Curve in Figure 2 to Figure 9. These derating curve are approximations of the ambient temperature and airflow required to keep the power module temperature below it's maximum rating. Once the module is assembled in the actual system, the module's temperature should be verified. Proper cooling can be verified by measuring the power module's temperature at Q1-pin 6 and Q2-pin 6 as shown in Figure 1. 3 NEA/NEF10_6200850000_B01_21/04/08 Murata Power Solutions Volant NEA/NEF010 Series Non-Isolated 10A SIP DC/DC Converters TYPICAL DERATING CURVES 12 NEF0100101B Derating Curve Output Current (A) 10 8 6 4 2 0 20 30 40 50 60 70 80 90 100 0LFM 100LFM 200LFM 300LFM Ambient Temperature (C) Figure 2.

If this product is built into information technology equipment, the installation must comply with the above standard. An external input fuse (no more than 20 Amps, recommended) must be used to meet the above requirements. The output of the converter [Vo(+)/Vo(-)] is considered to remain within SELV limits when the input to the converter meets SELV or TNV-2 requirements.
