Frequently asked questions
What does the -40°C to 85°C operating temperature mean for industrial enclosure deployment?
The TA suffix confirms the 85°C rating is ambient temperature — the part is specified to survive up to 85°C local ambient. A continuous industrial enclosure operating at 60°C ambient gives roughly 25°C thermal headroom, which satisfies IEC 60068-2-2 dry heat requirements for continuous operation in climate-controlled cabinets. Junction temperature will depend on board thermal design and I/O switching losses — thermal modelling is required before assuming the rating holds at full 180MHz load in a sealed enclosure.
