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."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/STM32F439ZGY6TR","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/STM32F439ZGY6TR when reusing this data.
