Importantnotes Thefollowingappliestoallproductsnamedinthispublication: 1. Somepartsofthispublicationcontainstatementsaboutthesuitabilityofourproductsfor certain areas of application. These statements are based on our knowledge of typical re- quirementsthatareoftenplacedonourproductsintheareasofapplicationconcerned.We nevertheless expressly point out that such statements cannot be regarded as binding statementsaboutthesuitabilityofourproductsforaparticularcustomerapplication. 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- bentonthecustomertocheckanddecidewhetheranEPCOSproductwiththepropertiesde- scribedintheproductspecificationissuitableforuseinaparticularcustomerapplication. 2. We also point out that in individual cases, a malfunction of electronic components or failurebeforetheendoftheirusualservicelifecannotbecompletelyruledoutinthe currentstateoftheart,eveniftheyareoperatedasspecified.Incustomerapplications 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.installationofprotectivecircuitryorredundancy)thatnoinjuryordamageissustainedby thirdpartiesintheeventofmalfunctionorfailureofanelectroniccomponent. 3.
