Different methods could be used to calculate the predicted MTBF and failure rate which may give different results. Ericsson Power Modules currently uses two different methods, Ericsson failure rate data system DependTool and Telcordia SR332. Predicted MTBF for the series is: million hours according to DependTool million hours according to TelCordia SR332, issue 1, Black box technique. The Ericsson failure rate data system is based on field tracking data. The data corresponds to actual failre rates of components used in Information Technology and Telecom (IT&T) equipment in temperature controlled environments (T A = C). Telcordia SR332 is a commonly used standard method intended for reliability calculations in IT&T equipment. The parts count procedure used in this method was originally modelled on the methods from MIL-HDBK-217F, Reliability Predictions of Electronic Equipment. It assumes that no reliability data is available on the actual units and devices for which the predictions are to be made, i.e. all predictions are based on generic reliability parameters. Compatibility with RoHS requirements The products are compatible with the relevant clauses and requirements of the RoHS directive 22/95/EC and have a maximum concentration value of.1% by weight in homogeneous materials for lead, mercury, hexavalent chromium, PBB and PBDE and of.1% by weight in homogeneous materials for cadmium. Exemptions in the RoHS directive utilized in Ericsson Power Modules products include: - Lead in high melting temperature type solder (used to solder the die in semiconductor packages) - Lead in glass of electronics components and in electronic ceramic parts (e.g. fill material in chip resistors) - Lead as an alloying element in copper alloy containing up to 4% lead by weight (used in connection pins made of Brass) Quality Statement The products are designed and manufactured in an industrial environment where quality systems and methods like ISO 9, 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. 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 persons health or life).

3 SEC/D Kevin Chen PRODUCT SPECIFICATION 3 (3) 1/131-BMR632 Technical Uen Specification 3 PKL 4 PI series D DC/DC converters, Input 36-, Output 1 A/3 W Safety Specification General information Ericsson Power Modules DC/DC converters and DC/DC regulators are designed in accordance with safety standards IEC/EN/UL695, Safety of Information Technology Equipment. IEC/EN/UL695 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 are defined as component power supplies. As components they cannot fully comply with the provisions of any Safety requirements without Conditions of Acceptability. 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 Directives for the final product. Component power supplies for general use should comply with the requirements in IEC695, EN695 and UL695 Safety of information technology equipment. There are other more product related standards, e.g. IEEE82.3af Ethernet LAN/MAN Data terminal equipment power, and ETS Power supply interface at the input to telecommunications equipment; part 2: DC, but all of these standards are based on IEC/EN/UL695 with regards to safety. Ericsson Power Modules DC/DC converters and DC/DC regulators are UL695 recognized and certified in accordance with EN695. The flammability rating for all construction parts of the products meets requirements for V- class material according to IEC The products should be installed in the end-use equipment, in accordance with the requirements of the ultimate application. Normally 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/UL695. Isolated DC/DC converters It is recommended that a slow blow fuse with a rating twice the maximum input current per selected product 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 in the input filter or in the DC/DC converter that imposes a short circuit on the input source, this fuse will provide the following functions: Isolate the faulty DC/DC converter 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 (V iso ) between input and output is 15 Vdc or 225 Vdc for 6 seconds (refer to product specification). Leakage current is less than 1 μa at nominal input voltage. 24 V DC 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 6 V DC systems If the input voltage to Ericsson Power Modules DC/DC converter is dc 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 dc. If the input power source circuit is a DC power system, the source may be treated as a TNV2 circuit and testing has demonstrated compliance with SELV limits and isolation requirements equivalent to Basic Insulation in accordance with IEC/EN/UL695. 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.
