1 Failure In Time (FIT) Rates

This section provides Failure In Time (FIT) rates for LMT86-Q1 based on two different industry-wide used reliability standard. Table 1-1 provides FIT rates based on IEC TR 62380 / ISO 26262 part 11.

Table 1-1 Component Failure Rates per IEC TR 62380 / ISO 26262 Part 11
FIT IEC TR 62380 / ISO 26262 FIT (Per 109 Hours)
Total Component FIT Rate 4
Die FIT Rate 2
Package FIT Rate 2
