How to Convert FIT to MTBF Sciencing

WebMTBF, FIT, and PPM Conversions. One of the most often used numbers in reliability is the mean time between failures (MTBF) number. MTBF represents the average time one can expect a device to operate without failing. There is no assurance that the consumer will realize this failure‐free time period because the MTBF is a statistical average. WebThe intent of this White Paper is to provide an understanding of MTBF and other product reliability methods.

WebAug 8, 2015 · Failures in Time, or ‘FIT’ rates are defined in ‘Failures per Billion Hours’ (FPBH). For our purposes, MTBF is typically expressed as a number of hours, years or some other measure of time. The relationships between these different data formats are illustrated in the conversion examples below. FPMH = FPBH*10 -3. Webthe MTBF: MTBF = 1 / λ or λ = 1 / MTBF If you now replace the failure rate λ in F(t), you get the following result: F(t) = 1 - (e -t/MTBF) the manufacturer and an assumed constant failure rate. Example After one year's delivery, there are 20,000 components in the field with an MTBF of 60 years.
