Orin nx thermal resistance


i am thermal engineer who want to simulate Orin nx in subsystems.
i have read the thermal design guide v1.0 and there are lake of information regarding thrmal resistance of the main component : T234 TE980-M
no Rj-c either no Rj-b

where can i found these numbers. which critical to thermal analysis


Welcome to the NVIDIA Developer forums. I am moving this topic to the Jetson category for visibility.


As you can see in the notes in TDG: For components, which do not show Rj-c and Rj-b values in the table. It should be modeled as a single block with bulk thermal conductivity specified in the table.

thank you for quick response.
but there is no value for that componet. see in the first raw in the table.
i attached picture.

Hi, there will be updates in next released TDG. For now, you can use below values.

Rjc [C/W] 0.145
Rjb [C/W] 1.544
