nrf9160 thermal resistance

[GiulianoFranchetto]

Hi,

What is the thermal resistance J-A of the nRF9160 ?

We need it for the ATEX compliance thermal analysis.

Hi!

So, for thermal resistance data, I can't find much. The thermal conductivity of the SiP is 35 C/W.

If you need the junction to ambient thermal resistance number specifically, I can try to find that out for you, just let me know. 

Best regards,

Heidi

Hi Heidi!

Any news on that ticket?

Hi! 

Yes, for thermal resistance junction to ambient, 35 C/W is the correct value. They will be adding this value to the ATEX compliance table in the nRF9160 PS V2.0.

Best regards,

Heidi
