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. WebMTTF on the other hand, is a projection of when the arithmetic mean time between failures of the whole population where it is an inverse of the FIT rate. The MTTF is orders of magnitudes higher than the useful life. 7 Limitations of This Document • This applies to the TMP temperature sensor family of devices.
