How much of a temperature increase are we talking about,
how much do emissions increase, and what frequency(s)
increase in emissions?

I am interested to find out peoples opinions on a particular trend we've
seen time and time again on most switch mode PSU's. It seems that once a PSU is
warm its earth leakage decreases and its EMC emission performance decreases
(i.e. it gets noisier). This would suggest that there is s
