THERMAL DATA
Natural Convection: 3.66 based on 70 C temp rise above ambient
Thermal resistance is calculated based on a single 1" (25.4mm) square heat source centered on the heat sink. If you have distributed
loads, then you can expect 10% better performance in natural convection and 20% better performance in forced convection.
