General Information
Reliability
The failure rate (
) and mean time between failures
(MTBF= 1/
) is calculated at max output power and an
operating ambient temperature (T
A
) of +40°C. Ericsson
Power Modules uses Telcordia SR-332 Issue 2 Method 1 to
calculate the mean steady-state failure rate and standard
deviation (
).
Telcordia SR-332 Issue 2 also provides techniques to
estimate the upper confidence levels of failure rates based
on the mean and standard deviation.
Mean steady-state failure rate,
425 nFailures/h
Std. deviation,
60.9 nFailures/h
MTBF (mean value) for the BMR456 series = 2.9 Mh.
MTBF at 90% confidence level = 2.4 Mh
