option
The products are designed and manufactured in an
industrial environment where quality systems and methods
like ISO 9000, 6σ (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 our products.

The failure rate (λ) and mean time between failures
The information and specifications in this technical
specification is believed to be correct at the time of
publication. However, no liability is accepted for
inaccuracies, printing errors or for any consequences
thereof. Ericsson AB reserves the right to change the
contents of this technical specification at any time without
prior notice.
(MTBF= 1/λ) 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 (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
Std. deviation, σ
146 nFailures/h
38.3 nFailures/h
MTBF (mean value) for the BMR451 series = 6.9 Mh.
MTBF at 90% confidence level = 5.1 Mh
