Hi.

Actually W7500P public temperature is 0 ~ 70 degree. (inside PHY temperature)

But, we tried temperature test to -40 to 85. (each test 240 hours)

So, temperature result is pass.

If you want temperature result documents, I send to you.

Thank you

Hi, is it possible to get a copy of the temperature result documents?
Relatedly, will the specification of the W7500P temperature range of operation change in the near future to reflect these tests?

Thanks!

Hi.

We tried temperature tests on WIZ750SR.
Please refer to attached file.
