MTBF interpretation
MTBF interpretation
(OP)
Hello,
If MTBF value is 120 yrs, and 7 units failed out 1200 units, how is this translated in to ppm or % wise?
Regards

RE: MTBF interpretation
MTBF will allow you to predict the probability of a part working based on a certain time. R(T)=exp(-T/MTBF) T is the time you're interested in and R(T) is the probability the part will work over that course of time.
Hope that helps answer part of your question.

A higher ambient temperature could easily double or quadruple the failure rate.
