General Information
Reliability
The failure rate (
) and mean time between failures
(MTBF= 1/
) 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 (
).
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,
425 nFailures/h
Std. deviation,
60.9 nFailures/h
MTBF (mean value) for the BMR456 series = 2.9 Mh.
MTBF at 90% confidence level = 2.4 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.
Exemptions in the RoHS directive utilized in Ericsson
Power Modules products are found in the Statement of
Compliance document.
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
warranties, expressed or implied including any warranty of
merchantability or fitness for a particular purpose
(including, but not limited to, use in life support
applications, where malfunctions of product can cause
injury to a person’s health or life).

Safety Specification
General information
Ericsson Power Modules DC/DC converters and DC/DC
regulators are designed in accordance with the safety
standards IEC 60950-1, EN 60950-1 and UL 60950-1
Safety of Information Technology Equipment.
IEC/EN/UL 60950-1 contains requirements to prevent injury
or damage due to the following hazards:
Electrical shock
Energy hazards
Fire
Mechanical and heat hazards
Radiation hazards

circuit on the input source, this fuse will provide the
following functions:
Isolate the fault from the input power source so as not
to affect the operation of other parts of the system
Protect the distribution wiring from excessive current
and power loss thus preventing hazardous overheating
The DC/DC converter output is considered as safety extra
low voltage (SELV) if one of the following conditions is met:
The input source has double or reinforced insulation
from the AC mains according to IEC/EN/UL 60950-1
The input source has basic or supplementary insulation
from the AC mains and the input of the DC/DC
converter is maximum 60 Vdc and connected to
protective earth according to IEC/EN/UL 60950-1
The input source has basic or supplementary insulation
from the AC mains and the DC/DC converter output is
connected to protective earth according to
IEC/EN/UL 60950-1
Non - isolated DC/DC regulators
The DC/DC regulator output is SELV if the input source
meets the requirements for SELV circuits according to
IEC/EN/UL 60950-1.
On-board DC/DC converters and DC/DC regulators are
defined as component power supplies. As components
they cannot fully comply with the provisions of any safety
requirements without “conditions of acceptability”.
Clearance between conductors and between conductive
parts of the component power supply and conductors on
the board in the final product must meet the applicable
safety requirements. Certain conditions of acceptability
apply for component power supplies with limited stand-off
(see Mechanical Information for further information). It is
the responsibility of the installer to ensure that the final
product housing these components complies with the
requirements of all applicable safety standards and
regulations for the final product.
Component power supplies for general use should comply
with the requirements in IEC/EN/UL 60950-1

Galvanic isolation between input and output is verified in an

the voltage strength requirement for basic insulation
according to IEC/EN/UL 60950-1.
It is recommended to use a slow blow fuse at the input of
each DC/DC converter. If an input filter is used in the circuit
the fuse should be placed in front of the input filter. In the

Stress in excess of Absolute Maximum Ratings may cause permanent damage. Absolute Maximum Ratings, sometimes referred to as no destruction limits, are
normally tested with one parameter at a time exceeding the limits of Output data or Electrical Characteristics. If exposed to stress above these limits, function and
performance may degrade in an unspecified manner.
