•
(a) device on insulated closed-cell foam pad, natural convection only on top and side surfaces.
•
(b) device on insulated closed-cell foam pad, ducted forced air cooling at 20.1 LFM on top and
side surfaces.
The temperature protection limit at 110 °C applies to the average internal device temperature. The
average device temperature is representative of the majority of PCBA components within the device.
The SoC within the device typically operates at a temperature delta of ~10°C above the average device
temperature and triggers overtemperature protection at a correspondingly higher temperature of
120°C.
