The baseline temperature in an electronic system is a very
important parameter for thermal design and must be carefully
considered. But the term ambient temperature has developed a lot
of ambiguity in its usage as well as its value. System and
component designers can greatly improve the accuracy of their
thermal considerations by clearly communicating what the
baseline temperature truly is for their implementation, and
finding a way to estimate the temperatures at or close to the
components of interest. What is Ambient Temperature? Thermal
analysis is an essential part of nearly all electronic system
designs these days. We have to make sure that the components do
not heat up so much as to affect their functionality or make the
system practically unusable. And for most of us, it’s a delicate
dance of environmental factors, system design, component power
dissipation, and a range of usage conditions. We must establish
some baseline temperature conditions, then figure out through
modeling, calculations, rules of
