MIL-HDBK-217 MTBF: Greater than 20,000 hours
MTBF Definition:
Mean time between failures (MTBF) is calculated following MIL-HDBK-217 guidance as a starting point, when
available field or vendor data is used in place of MIL-HDBK-217 predictions. The AIS-380 prediction is for an
environment of airborne, inhabited, cargo. At 20°C the prediction is 36,367 hours and at 40°C it is 22,607
hours.
