Ericsson Power Modules 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.
Quality Statement
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.
Warranty
Warranty period and conditions are defined in Ericsson
Power Modules General Terms and Conditions of Sale.
Limitation of Liability
Ericsson Power Modules does not make any other

General Information
Reliability
The failure rate (
λ
) and mean time between failures
(MTBF= 1/
λ
) 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 (
σ
).
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,
λ
233 nFailures/h
Std. deviation,
σ
34.6 nFailures/h
MTBF (mean value) for the PKB-A series = 4.3 Mh.
MTBF at 90% confidence level = 3.6 Mh
Compatibility with RoHS requirements
The products are compatible with the relevant clauses and
requirements of the RoHS directive 2002/95/EC 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.
Exemptions in the RoHS directive utilized in Ericsson
Power Modules products are found in the Statement of
Compliance document.
