Thermal characteristics

1  

All values are calculated by simulating the test method using a wind tunnel according to the JEDEC standard. Air velocity of 0 m/s represents natural convection under still air in the wind tunnel specified in the JEDEC standard.
2 Thermal characteristics are affected by environmental conditions such as the density of the copper pattern on the test board, etc.
