MTTF is frequently used interchangeably with MTBF rating: The Arrhenius model will be used to determine the acceleration factor for failure mechanisms that are temperature accelerated. AfT = exp((Ea/k)*(1/Tu - 1/Ts)) = tu/ts AfT = Acceleration factor due to Temperature tu = Time at use temperature ( |
