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
uses Telcordia SR-332 Issue 3 Method 1 to calculate the
mean steady-state failure rate and standard deviation ().
Telcordia SR-332 Issue 4 also provides techniques to
estimate the upper confidence levels of failure rates based
on the mean and standard deviation.
Mean steady-state failure rate,
MTBF (mean value) for the PKU4611A series = 5.2 Mh.
MTBF at 90% confidence level = 4.6 Mh
Flex Power fulfills and will continuously fulfill all its
obligations under regulation (EC) No 1907/2006 concerning
the registration, evaluation, authorization and restriction of
chemicals (REACH) as they enter into force and is through
product materials declarations preparing for the obligations
to communicate information on substances in the products.
The products are designed and manufactured in an
industrial environment where quality systems and methods
like ISO 9000, Six Sigma, and SPC are intensively in use to
boost the continuous improvements strategy. Infant
mortality or early failures in the products are screened out
and they are subjected to an ATE-based final test.
Conservative design rules, design reviews and product
qualifications, plus the high competence of an engaged
work force, contribute to the high quality of the products.
