How do I calculate the Mean Time between Failure (MTBF) for Altera devices? - How do I calculate the Mean Time between Failure (MTBF) for Altera devices? Description The Mean Time between Failure (MTBF) is simply the inverse of the failure rate for an exponential distribution while the Failure in Time (FIT) rate is 10^9 x failure rate MTBF = 1/failure rate Example: If FIT = 15.1, then MTBF = 10^9/15.1 = 66225165 Related Articles Where can I find the Failure in Time (FIT) rate for Altera devices?
