Technical Reference Table 36 provides maximum case temperatures for the board components that are sensitive to thermal changes. The operating temperature, current load, or operating frequency could affect case temperatures. Maximum case temperatures are important when considering proper airflow to cool the board. Table 36.

Reliability
The Mean Time Between Failures (MTBF) prediction is calculated using component and
subassembly random failure rates.
The calculation is based on the Bellcore Reliability
Prediction Procedure, TR-NWT-000332, Issue 4, September 1991.
The MTBF
prediction is used to estimate repair rates and spare parts requirements.
The MTBF data is calculated from predicted data at 55 ºC.
The Desktop Board
DG965MQ MTBF is 105,367 hours.
