8.1 Mean Time between Failure
The following is the calculated Mean Time Between Failures (MTBF) at maximum configuration
at 40C (ambient air). These values are derived using a historical failure rate and multiplied by
factors for application, electrical and/or thermal stress and for device maturity. MTBF estimates
should be viewed as “reference numbers” only.
