8XC51FX
Thermal Impedance
All thermal impedance data is approximate for static
air conditions at 1W of power dissipation Values will
change depending on operating conditions and ap-
plications See the Intel Packaging Handbook (Order
No 240800) for a description of Intel’s thermal im-
pedance test methodology
