9 08/08 please read cautions and warnings and important notes at the end of this document. general also see ?important notes? on page 11. 1 aluminum electrolytic capacitors have a bi-polar structure. this is marked on the body of the capacitor. a capacitor must not be mounted with reversed polarity. the application of an ac or reverse voltage may cause a short circuit or damage the capacitor. bi-polar capacitors must not be used in ac applications, where the pol arity may be reversed in the circuits or is unknown. 2 the dc voltage applied to the capacitor terminal must not exceed its rated operating voltage, as this will result in a rapid increase of the leakage current and may damage the capacitor. it is recommended to operate the capacitor at 70?80% of its rated voltage to optimize its serv- ice life. 3 the ripple current applied to the capacitor must be within the permitted range. an excessive ripple current leads to impaired electrical properties and may damage the capacitor. note that the sum of the peak values of the ripple voltage and the dc operating voltage must not ex- ceed the rated dc voltage. 4 capacitors must be used within their permitted range of operating temperature. operation at room temperature optimizes their service life. 5 capacitors with case diameter 8 mm are equipped with a safety vent. in capacitors fitted with a lead or soldering lug, the safety vent is usually located at the base of the case. it needs sufficient space around it to operate optimal ly. the following dimensions are recommended: for case diameter d = 8 to 16 mm, more than 2 mm; for d =18 to 35 mm, more than 3 mm; and for d = 42 mm or more, more than 5 mm. 6 capacitors should not be mounted with the safety vent face down on the board. do not locate any wire or copper trace near the safety vent. do not reverse the voltage, as this may result in excess pressure and the leakage of electrolyte. 7 gas is released through the safety vent when t he pressure inside the capacitor is too high. a gaseous liquid around the safety vent does not indicate a leakage of electrolyte. 8 the capacitor should be stored under conditions of normal temperature and in a non-acid, non-alkali environment of normal humidity. ex posure to high temperatures, for example un- der direct sunlight, will reduce its operating life. if the capacitor is stored in an environment containing acids or alkalis, the solder ability of the leads may be affected. 9 the leakage current of an alumi num electrolytic capacitor ma y increase after a long period of storage. after such storage, the capacitor must be aged by applying the rated operating voltage for 6?8 hours before use. 10 manual soldering: a soldering must be performed within the specified conditions. bit temperature: 350 c; application time of soldering iron: 3 seconds. b ensure that the soldering iron does not touch any part of the capacitor body. cautions and warnings aec-c_b42002_B42021.book seite 9 dienstag, 5. august 2008 4:26 16
cautions and warnings 10 08/08 please read cautions and warnings and important notes at the end of this document. 11 do not apply excessive force to the leads and te rminals. do not move the capacitor after sol- dering it onto the pc board and do not carry the pc board by gripping the capacitor. observe the following rules to prevent undue stress to the capacitor: a do not tilt or bend the capacitor after soldering. b ensure that the terminal spacing matc hes the corresponding hole spacing on the pc board. 12 the aluminum case is not insulated from the cathode. do not place a conductor under the aluminum capacitors on the pc board as this may cause a short circuit. the case and top of capacitors used in switched mode power supplie s have a high-voltage-resistant heat shrink sleeve to ensure safe usage. 13 the leads of capacitors with a case diam eter exceeding 14 mm cannot be used for fixing. aec-c_b42002_B42021.book seite 10 dienstag, 5. august 2008 4:26 16
important notes 11 08/08 important notes the following applies to all produc ts 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 requirements that are often placed on our produc ts 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 produc ts for a particular customer application. as a rule, epcos is either unfamiliar with individual customer applicatio ns or less familiar with them than the customers themselves. for these reasons , it is always ultimately incumbent on the customer to check and decide whether an epcos product with the properties described in the product specification is suitable for us e 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 applic ations in which the malfunction or failure of an electronic component could endanger human life or health (e.g. in accident prevention or life-saving systems), it must t herefore 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 material data sheets on the internet (www .epcos.com/material). should you have any more detailed questions, please contact our sales offices. 5. we constantly strive to im prove 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 c heck therefore to what extent pr oduct descriptions an d specifications contained in this publicati on 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 al ways be available. the aforementioned does not apply in case of individ ual agreements deviating from the foregoing for customer-specific products. 6. unless otherwise agreed in individual contracts, all orders are subject to the current version of the ?general terms of delivery for products and services in the electrical industry? published by the german electrical and electronics industry association (zvei) . 7. the trade names epcos, baoke, alu-x, cera diode, cssp, ctvs, dssp, miniblue, mkk, mlsc, motorcap, pcc, phasecap, phasemod, siferrit, sifi, sikorel, silvercap, simdad, simid, sineformer, siov, si p5d, 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. aec-c_b42002_B42021.book seite 11 dienstag, 5. august 2008 4:26 16
