(1) For more information about traditional and new thermal metrics, see the IC Package Thermal Metrics application report, SPRA953.
(2) Estimated when mounted on high K JEDEC board per JESD 51-7 with thickness of 1.6 mm, 4 layers, size of 76.2 mm × 114.3 mm, and
2-oz. copper for top and bottom plane. Actual thermal impedance will depend on PCB used in the application.
