Hello Rowan

Kindly refer to below information

Based upon life 
testing, in the amounts as prescribed by AEC-Q100, with 0 failures found, we 
can calculate a failure rate <10FIT, with 60% Confidence Level, at a 
junction temperature of 55°C with an activation energy of 0.7eV.  This 
failure rate equals an MTBF > 100M hours. These figures are sample size 
limited. 

Based upon 
justified field returns, so excluding EOS/ESD and NTF, we can calculate an 
experienced field failure rate << 1FIT. For this calculation we assume 
1.5 hours of operation per day, for each delivered product, this equals a 
typical automotive profile.

Have a great day,
Becky
