Fit and mttf

WebMTBF/MTTF is the reciprocal of FIT. Below is the equation to illustrate this. Based on this formula, lower failure rate would equate to higher mean time to failure. WebMTBF. The FIT is equivalent to one failure per billion device hours, which is equivalent to a MTBF of 1,000,000,000 hours. The formula for calculating the MTBF is = T/R. = MTBF T = total time R = number of failures MTTF is stands for Mean Time To Failure. To distinguish between the two, the concept of suspensions must first be understood.

Webthe FIT Rate* is * The FIT rate is determined by calculating the cumulative fraction fail over the expected life, based on a lognormal distribution. This failure rate is extrapolated to calculate a new MTTF. The FIT rate is then calculated according to the standard formula -- FIT = 1E9/MTTF. This approach will result in a more accurate and ...
