"WebThe MTBF value (= Mean Time Between Failure) is defined as the time between two errors of an assembly or device. Typical values lie between 300‘000 and 1‘200‘000 hours. Failure rates are identified by means of life testing experiments and experience from the field. The MTBF results from the inverse FIT or λ values. " - Fit and mtbf
