7.4 Thermal Information

The value of R_θJA given in this table is only valid for comparison with other packages and cannot be used for design purposes. These values were calculated in accordance with JESD 51-7, and simulated on a 4-layer JEDEC board. They do not represent the performance obtained in an actual application. For example, with a 4-layer PCB, a R_ΘJA = 25℃/W can be achieved.
