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. Flex 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,
118 nFailures/h
Std. deviation,
8.6 nFailures/h
MTBF (mean value) for the PKB 4111D series = 9.33 Mh.
MTBF at 90% confidence level = 8.47 Mh
Compatibility with RoHS requirements
The products are compatible with the relevant clauses and
requirements of the RoHS directive 2011/65/EU and have a
maximum concentration value of 0.1% by weight in
homogeneous materials for lead, mercury, hexavalent
chromium, PBB and PBDE and of 0.01% by weight in
homogeneous materials for cadmium.
