6.0 THERMAL CHARACTERISTICS
All thermal impedance data is approximate for static
air conditions at 1 watt of power dissipation. Values
change depending on operating conditions and
application requirements. The Intel Packaging
Handbook (order number 240800) describes Intel’s
thermal impedance test methodology.
