General Information
Reliability
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 uses
Telcordia SR-332 Issue 3 Method 1 to calculate the mean
steady-state failure rate and standard deviation ().
Telcordia SR-332 Issue 3 also provides techniques to
estimate the upper confidence levels of failure rates based
on the mean and standard deviation.
Mean steady-state failure rate,
118 nFailures/h
Std. deviation,
9.1 nFailures/h
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 Flex General
Terms and Conditions of Sale.
Limitation of Liability
Flex 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).

MTBF (mean value) for the PKB 4413D series = 8.50 Mh.
MTBF at 90% confidence level = 7.73 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 Flex products
are found in the Statement of Compliance document.
Flex 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.

Safety Specification
General information
Flex Power DC/DC converters and DC/DC regulators are
designed in accordance with the safety standards
IEC 62368-1, EN 62368-1 and UL 62368-1 Audio/video,
information and communication technology equipment -
Part 1: Safety requirements
IEC/EN/UL 62368-1 contains requirements to prevent injury
or damage due to the following hazards:
Electrical shock
Electrically-caused fire
Injury caused by hazardous substances
Mechanically-caused injury
Skin burn
Radiation-caused injury
On-board DC/DC converters, Power interface modules 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 shall comply
with the requirements in IEC/EN/UL 62368-1. Product
related standards, e.g. IEEE 802.3af Power over Ethernet,
and ETS-300132-2 Power interface at the input to telecom
equipment, operated by direct current (dc) are based on
IEC/EN/UL 60950-1 with regards to safety.
Flex Power DC/DC converters, Power interface modules
and DC/DC regulators are UL 62368-1 recognized and
certified in accordance with EN 62368-1. 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.
Isolated DC/DC converters
The product may provide basic or functional insulation
between input and output according to IEC/EN/UL 62368-1
(see Safety Certificate), different conditions shall be met if
the output of a basic or a functional insulated product shall
be considered as ES1 energy source.
following conditions is met:
The input source provides supplementary or double or
reinforced insulation from the AC mains according to
IEC/EN/UL 62368-1.
The input source provides functional or basic insulation
from the AC mains and the product’s output is reliably
connected to protective earth according to
IEC/EN/UL 62368-1.
For functional insulated products (see Safety Certificate)
the output is considered as ES1 energy source if one of the
following conditions is met:
The input source provides double or reinforced
insulation from the AC mains according to
IEC/EN/UL 62368-1.
The input source provides basic or supplementary
insulation from the AC mains and the product’s output is
reliably connected to protective earth according to
IEC/EN/UL 62368-1.
The input source is reliably connected to protective
earth and provides basic or supplementary insulation
according to IEC/EN/UL 62368-1 and the maximum
input source voltage is 60 Vdc.
Galvanic isolation between input and output is verified in an
electric strength test and the isolation voltage (Viso) meets
the voltage strength requirement for basic insulation
according to IEC/EN/UL 62368-1.
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
rare event of a component problem that imposes a short
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
For basic insulated products (see Safety Certificate) the
output is considered as ES1 energy source if one of the
