Jetson Orin NX – Clarification on Maximum Ambient Temperature for Operation and Storage

[CEZWA18]

Hi Team,

I need clarification on the maximum ambient temperature limits for the Jetson Orin NX module.

My hardware team currently assumes that the maximum ambient operating temperature is 45 °C. However, I’ve seen different values mentioned across vendor datasheets and partner boards (some showing +55 °C or even up to +70 °C)

Could you please confirm:

1. What is the official ambient operating temperature range for Jetson Orin NX SoM (standard model)? both storage and Operting
2. What is the recommended ambient storage temperature range for the module?
3. Does the +45 °C limit apply only to certain carrier boards or configurations?

We’re planning to deploy Orin NX in an environment where the ambient may approach 50–55 °C, so it’s important to understand the limitations at the module level vs system level.

Thanks in advance.

Best regards,
Cezwa

I’d be happy to help clarify the operating temperature limits for the Jetson Orin NX module.

Unfortunately, the provided context does not explicitly mention the operating temperature limits for the Jetson Orin NX module. However, I can provide some general information and insights that might be helpful.

The context mentions that the thermal model for the Orin package is based on “Uniform heat loading of die,” and designers must account for adequate margin when designing a thermal solution. This suggests that the operating temperature limits might depend on various factors, including the specific use case, workload, and thermal design.

The context also mentions that the thermal specifications are preliminary estimates and will be updated in the next release. This implies that the current information might not be final, and it’s essential to consult the latest documentation or contact NVIDIA directly for the most up-to-date information.

Regarding the values mentioned in vendor datasheets and partner boards, it’s possible that these values are specific to certain configurations or carrier boards. Without more information, it’s difficult to determine whether these values are applicable to the Jetson Orin NX module.

To confirm the operating temperature limits for the Jetson Orin NX module, I recommend consulting the official NVIDIA documentation or contacting their support team directly. They should be able to provide more detailed information on the operating temperature limits, including any specific requirements or recommendations for the module.

In general, it’s essential to consider the operating temperature limits at both the module and system levels, especially when deploying the module in an environment with high ambient temperatures. Ensuring that the module operates within its specified temperature range is crucial for maintaining its performance, reliability, and lifespan.

I hope this information helps, and I recommend seeking further clarification from NVIDIA directly.

Thanks and appreciate your reply, am am not able to trace any ambient temperature limitation for the Orin NX from the datasheet or Thermal design guide.
I did contacted the chat support they redirected me to post in forum…

What i wanted to understand is, does the ambient temperature is limited because of the storage temperature or even for operating also it is limited.

If using developer kit, please refer to carrier board specification https://developer.nvidia.com/downloads/assets/embedded/secure/jetson/orin_nano/docs/jetson_orin_nano_devkit_carrier_board_specification_sp.pdf

For the Jetson Orin NX module, please refer to the data sheet https://developer.nvidia.com/downloads/jetson-orin-nx-module-series-data-sheet

For Thermal Design Guide, please refer to https://developer.nvidia.com/downloads/jetson-orin-nx-orin-nano-series-thermal-design-guide

Actual operating temperature range will depend on your thermal solution. As long as you are able to keep Orin SOC Tj below 99C with some margin and the Tcase for the key components (like 85C for LPDDR5) below their specifications in the thermal design guide, the thermal solution will decide the higher operating temperature limit in your design.
