General Information
Reliability
The failure rate () and mean time between failures
(MTBF= 1/) is calculated at max output power and an
operating ambient temperature (TA) 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 leve ls of failure rates based
on the mean and standard deviation.
Mean steady-state failure rate, Std. deviation,
421 n Failures/h 60.9 nFailures/h
MTBF (mean value) for the BMR457 series = 2.91 Mh.
MTBF at 90% confidenc e level = 2.37 Mh
Compatibility with RoHS requirements
The products are compatible wit h the rel evant clauses and
requirements of the RoHS directive 2011/65/EU and have a
maximum concentration value of 0.1% b y weight in
homogeneous materials for lead, mercury, hexavalent
chromium, PBB and PBDE and of 0.01% by weight in
