cautions and warnings personal safety the electrolytes used by epcos have not only been optimized with a view to the intended application, but also with regard to health and environmental compatibility. they do not contain any solvents that are detrimental to health, e.g. dimethyl formamide (dmf) or dimethyl acetamide (dmac). furthermore, part of the high-voltage electrolytes used by epcos are self-extinguishing. they contain flame-retarding substances which will quickly extinguish any flame that may have been ignited. as far as possible, epcos does not use any dangerous chemicals or compounds to produce operating electrolytes. however, in exceptional cases, such materials must be used in order to achieve specific physical and electrical properties because no safe substitute materials are currently known. however, the amount of dangerous materials used in our products has been limited to an absolute minimum. nevertheless, the following rules should be observed when handling al electrolytic capacitors: any escaping electrolyte should not come into contact with eyes or skin. if electrolyte does come into contact with the skin, wash the affected parts immediately with running water. if the eyes are affected, rinse them for 10 minutes with plenty of water. if symptoms persist, seek medical treatment. avoid breathing in electrolyte vapor or mists. workplaces and other affected areas should be well ventilated. clothing that has been contaminated by electrolyte must be changed and rinsed in water. b41252 standard series 105 c page 14 of 19 please read cautions and warnings and important notes at the end of this document.
product safety the table below summarize the safety instructions that must be observed without fail. a detailed description can be found in the relevant sections of chapter "general technical information". topic safety information reference chapter "general technical information" polarity make sure that polar capacitors are connected with the right polarity. 1 "basic construction of aluminum electrolytic capacitors" reverse voltage voltages polarity classes should be prevented by connecting a diode. 3.1.6 "reverse voltage" upper category temperature do not exceed the upper category temperatur. 7.2 "maximum permissible operating temperature" maintenance make periodic inspections of the capacitors. before the inspection, make sure that the power supply is turned off and carefully discharge the electricity of the capacitors. do not apply any mechanical stress to the capacitor terminals. 10 "maintenance" mounting position of screw terminal capacitors do not mount the capacitor with the terminals (safety vent) upside down. 11.1 "mounting positions of capacitors with screw terminals" mounting of single-ended capacitors the internal structure of single-ended capacitors might be damaged if excessive force is applied to the lead wires. avoid any compressive, tensile or flexural stress. do not move the capacitor after soldering to pc board. do not pick up the pc board by the soldered capacitor. do not insert the capacitor on the pc board with a hole space different to the lead space specified. 11.4 "mounting considerations for single-ended capacitors" robustness of terminals the following maximum tightening torques must not be exceeded when connecting screw terminals: m5: 2 nm m6: 2.5 nm 11.3 "mounting torques" soldering do not exceed the specified time or temperature limits during soldering. 11.5 "soldering" b41252 standard series 105 c page 15 of 19 please read cautions and warnings and important notes at the end of this document.

the following applies to all products named in this publication: 1. some parts of this publication contain statements about the suitability of our products for certain areas of application . these statements are based on our knowledge of typical re- quirements that are often placed on our products in the areas of application concerned. we nevertheless expressly point out that such statements cannot be regarded as binding statements about the suitability of our products for a particular customer application . as a rule, epcos is either unfamiliar with individual customer applications or less familiar with them than the customers themselves. for these reasons, it is always ultimately incum- bent on the customer to check and decide whether an epcos product with the properties de- scribed in the product specification is suitable for use in a particular customer application. 2. we also point out that in individual cases, a malfunction of electronic components or failure before the end of their usual service life cannot be completely ruled out in the current state of the art, even if they are operated as specified . in customer applications requiring a very high level of operational safety and especially in customer applications in which the malfunction or failure of an electronic component could endanger human life or health (e.g. in accident prevention or lifesaving systems), it must therefore be ensured by means of suitable design of the customer application or other action taken by the customer (e.g. installation of protective circuitry or redundancy) that no injury or damage is sustained by third parties in the event of malfunction or failure of an electronic component. 3. the warnings, cautions and product-specific notes must be observed. 4. in order to satisfy certain technical requirements, some of the products described in this publication may contain substances subject to restrictions in certain jurisdictions (e.g. because they are classed as hazardous) . useful information on this will be found in our ma- terial data sheets on the internet (www.epcos.com/material). should you have any more de- tailed questions, please contact our sales offices. 5. we constantly strive to improve our products. consequently, the products described in this publication may change from time to time . the same is true of the corresponding product specifications. please check therefore to what extent product descriptions and specifications contained in this publication are still applicable before or when you place an order. we also reserve the right to discontinue production and delivery of products . consequently, we cannot guarantee that all products named in this publication will always be available. the aforementioned does not apply in the case of individual agreements deviating from the fore- going for customer-specific products. 6. unless otherwise agreed in individual contracts, all orders are subject to the current ver- sion of the "general terms of delivery for products and services in the electrical in- dustry" published by the german electrical and electronics industry association (zvei) . 7. the trade names epcos, baoke, alu-x, ceradiode, cssp, ctvs, dssp, miniblue, mkk, mlsc, motorcap, pcc, phasecap, phasemod, siferrit, sifi, sikorel, silvercap, simdad, simid, sineformer, siov, sip5d, sip5k, thermofuse, windcap are trademarks registered or pending in europe and in other countries. further information will be found on the internet at www.epcos.com/trademarks. important notes page 19 of 19
