General Information
Reliability
The failure rate () and mean time between failures (MTBF= 1/) is
calculated at max output power and an operating ambient tempera-
ture (TA) of +40°C. Murata 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, Std. deviation,
71 nFailures/h
12.7 nFailures/h
MTBF (mean value) for the OKDx series = 14.2 Mh.
MTBF at 90% confidence level = 11.52 Mh
Compatibility with RoHS requirements
The products are compatible with the relevant clauses and require-
ments 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 Murata Power Solutions
products are found in the Statement of Compliance document.
Murata Power Solutions fulfills and will continuously fulfill all its
obligations under regulation (EC) No 1907/2006 concerning the regis-
tration, 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 sub-
stances in the products.
Quality Statement
The products are designed and manufactured in an industrial environ-
ment 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 Murata Power Solutions
General Terms and Conditions of Sale.

Limitation of Liability
Murata Power Solutions 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)
The information and specifications in this technical specification is

thereof. Murata reserves the right to change the contents of this
technical specification at any time without prior notice.
Safety Specification
General information
Murata Power Solutions DC-DC converters and DC-DC regulators are
designed in accordance with safety standards IEC/EN/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
Chemical hazards
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 conduc-
tive parts of the component power supply and conductors on the
board in the final product must meet the applicable safety require-
ments. 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 require-
ments of all applicable safety standards and regulations for the final
product.
Component power supplies for general use should comply with the
requirements in IEC 60950 1, EN 60950 1 and UL 60950 1 Safety of
Information Technology Equipment.
There are other more product related standards, e.g. IEEE 802.3
CSMA/CD (Ethernet) Access Method, and ETS 300132 2 Power supply
interface at the input to telecommunications equipment, operated by
direct current (dc), but all of these standards are based on IEC/EN/UL
60950 1 with regards to safety.
Murata Power Solutions DC-DC converters and DC-DC regulators
are UL 60950 1 recognized and certified in accordance with EN 60950 1.

The flammability rating for all construction parts of the products
meet requirements for V 0 class material according to IEC 60695 11
10, Fire hazard testing, test flames – 50 W horizontal and vertical
flame test methods.
The products should be installed in the end-use equipment, in
accordance with the requirements of the ultimate application. Nor-
mally the output of the DC-DC converter is considered as SELV (Safety
Extra Low Voltage) and the input source must be isolated by minimum
Double or Reinforced Insulation from the primary circuit (AC mains) in
accordance with IEC/EN/UL 60950 1.
Isolated DC-DC converters
It is recommended that a slow blow fuse is to be used 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 rare event of a component problem that imposes a short cir-
cuit 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 galvanic isolation is verified in an electric strength test. The
test voltage (Viso) between input and output is 1500 Vdc or 2250 Vdc
(refer to product specification).

PRELIMINARY
24 VDC systems
The input voltage to the DC-DC converter is SELV (Safety
Extra Low Voltage) and the output remains SELV under normal and
abnormal operating conditions.
48 and 60 VDC systems
If the input voltage to the DC-DC converter is 75 Vdc or less, then the
output remains SELV (Safety Extra Low Voltage) under normal and
abnormal operating conditions.
Single fault testing in the input power supply circuit should be
performed with the DC-DC converter connected to demonstrate that
the input voltage does not exceed 75 Vdc.
If the input power source circuit is a DC power system, the source
may be treated as a TNV-2 circuit and testing has demonstrated com-
pliance with SELV limits in accordance with IEC/EN/UL60950-1.
Non-isolated DC-DC regulators
The input voltage to the DC-DC regulator is SELV (Safety Extra Low
Voltage) and the output remains SELV under normal and abnormal
operating conditions.
