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 Intel Desktop Board
DG41CN MTBF is 237,188 hours.
