I know that most of the power supply manufacturers, give data on room temperature (25C). Every (95%) power supply data sheet has MTBF at 25C. Is there a way we can calculate this number at higher temperature?? I would like to calculate this at 75C.

I am not looking exact number (in terms of years) but at-least rough estimate.

Any help would be greatly appreciated.

Thank you,
