THERMAL DATA
Natural Convection: 1.38 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.
