(1) Sample size is too small to provide meaningful FIT.
(2) FIT by Process technology below, refer to LTC Reliability Data Pack:
http://www.linear.com/designtools/quality/Rel_Data_Pack.pdf
(3) Assumes Activation Energy = 0.7 Electron Volts
(4) Failure Rate Equivalent to +55°C, 60% Confidence Level = 11.76 FITS
(5) Mean Time Between Failures in Years = 9,703
(6) Environmental data presented for same Process Technology.
Mechanical tests preceeded by J-STD-020 Preconditioning.
Note: 1 FIT = 1 Failure in One Billion Hours.
