FAILURE IN TIME (FIT)
CALCULATION METHOD:
According to Yageo calculation, assuming components life time is following exponential distribution and using
60% confidence interval (60% C.I.) in Homogeneous Poisson Process; therefore the FIT is calculated by number
of tested Failure in Endurance Test (rated power at 70°C for 1,000 hours, “IEC 60115-1 4.25.1”) as following:
