Heat conductivity
Power dissipation and maximum component temperature rise
The power dissipation must be limited in order not to exceed the maximum allowed component temperature rise as a
function of the free air ambient temperature.
The power dissipation can be calculated according chapter
“Introduction”
, section
“Maximum power dissipation”
.
The component temperature rise (DT) can be measured (see section “Measuring the component temperature” for more
details) or calculated by
:
T
=
component temperature rise (
°
C).
P
=
power dissipation of the component (mW).
G
=
heat conductivity of the component (mW/
°
C).
