2.7 Reliability
The Mean Time between Failures (MTBF) predictions are calculated using component and
subassembly random failure rates. The calculation is based on the Telcordia SR-332, Issue 2,
Method I, Case 3, 55 ºC ambient. The MTBF prediction is used to estimate repair rates and spare
parts requirements. The MTBF for Intel NUC10i3FNB board is 273,271 hours. The MTBF for Intel
NUC10i5FNB board is 273,153 hours. The MTBF for Intel NUC10i7FNB board is 272,416 hours.

The operating temperature of the board may be determined by measuring the air
temperature from the junction of the heatsink fins and fan, next to the attachment screw,
in a closed chassis, while the system is in operation.

Note: Before attempting to operate this board, the overall temperature of the board must be above the minimum
operating temperature specified. It is recommended that the board temperature be at least room temperature
before attempting to power on the board. The operating and non-operating environment must avoid condensing
humidity.
