Notes:
1. The point typical MTBF (which repre-
sents 60% confidence level) is the total
device hours divided by the number of
failures. In the case of zero failures, one
failure is assumed for this calculation.
2. The 90% Confidence MTBF represents
the minimum level of reliability perfor-
mance which is expected from 90% of
all samples. This confidence interval is
based on the statistics of the distribu-
tion of failures. The assumed
distribution of failures is exponential.
This particular distribution is com-
monly used in describing useful life
failures. Refer to MIL-STD-690B for
details on this methodology.
3. Failures are catastrophic or parametric.
Catastrophic failures are open, short,
no logic output, no dynamic parameters
while parametric failures are failures to
meet an electrical characteristic as
specified in product catalog such as
output voltage, duty or state errors.
Example of Failure Rate Calculation
Assume a device operating 8 hours/day, 5 days/week. The utilization factor, given 168 hours/week is:
(8 hours/day) x (5 days/week) / (168 hours/week) = 0.25
The point failure rate per year (8760 hours) at 50
°
C ambient temperature is:
(0.020% / 1K hours) x 0.25 x (8760 hours/year) = 0.044% per year
Similarly, 90% confidence level failure rate per year at 50
°
C:
(0.054% / 1K hours) x 0.25 x (8760 hours/year) = 0.118% per year
