Notes:
1. The point MTTF is simply the total
device hours divided by the number of
failures.
2. The MTTF and failure rate represent the
performance level for which there is a
90% probability of the device doing

better than the stated value. The
confidence level is based on the
statistics of failure distribution. The
assumed distribution is exponential.
This particular distribution is commonly
used in describing useful life failures.
3. FIT is defined as Failure in Time, or
specifically, failures per billion hours.
The relationship between MTTF and FIT
is as follows: FIT = 10

/(MTTF).
C. Example of Failure Rate Calculation
At 75
°
C with a device operating 8 hours a day, 5 days a week, the percent utilization is:
% Utilization = (8 hrs/day x 5 days/wk)
÷
168 hrs/wk = 25%
Then the point failure rate per year is:
(1.0 x 10
-10
/hr.) x (25%) x (8760 hrs/yr) = 2.2 x 10
-5
% per year
Likewise, the 90% confidence level failure rate per year is:
(2.3 x 10
-10
/hrs.) x (25%) x (8760 hrs/yr) = 5.1 x 10
-5
% per year
