10.1 Mean Time Between Failure
The following is the calculated Mean Time Between Failures (MTBF) at maximum configuration
at 35 C. 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.
