ceramic transient voltag e suppressors b72510h1140s272 smd multilayer varistor for high temp erature application CN0805S14BAUTOHTG2 kb vs pe 2009-07-16 please read cautions and warnings and page 8 of 12 important notes at the end of this document . cautions and warnings general some parts of this publication contain statements about the suitability of our ceramic transient voltage suppressor (ctvs) components (multilayer varistors (mlvs), ceradiodes, esd/emi filters, smd disk varistors (cu types), leaded transient voltage/ rfi suppressors (shcv types)) for certain areas of application, including recommendations about incorporation/design-in of these products into customer applications. the statements are based on our knowl edge of typical requirements often made of our ctvs devices in the particular areas. we neverthel ess expressly point out that such statements cannot be regarded as binding statements about the suitability of our ctvs components for a particular customer application. as a rule, epcos is either unfamiliar with individual customer applications or less familiar with them than the cust omers themselves. for these reasons, it is always incumbent on the customer to check and decide whether the ctvs devices with the properties described in the product specification are suitable for use in a particular customer application. ? do not use epcos ctvs components for purposes not identified in our specifications, application notes and data books. ? ensure the suitability of a ctvs in particular by testing it for reliability during design-in. always evaluate a ctvs component under worst-case conditions. ? pay special attention to the reliability of ctvs devices intended for use in safety-critical applications (e.g. medical equipment, automotive, spacecraft, nuclear power plant). design notes ? always connect a ctvs in parallel with the electronic circuit to be protected. ? consider maximum rated power dissipation if a ctvs has insufficient time to cool down between a number of pulses occurring within a specified isolated time period. ensure that electrical characteristics do not degrade. ? consider derating at higher operating temperatures. choose the highest voltage class compatible with derating at higher temperatures. ? surge currents beyond specified values will puncture a ctvs. in extreme cases a ctvs will burst. ? if steep surge current edges are to be expected, make sure your design is as low-inductance as possible. ? in some cases the malfunctioning of passive electronic components or failure before the end of their service life cannot be completely ruled out in the current state of the art, even if they are operated as specified. in applications requiring a very high level of operational safety and especially when the malfunction or failure of a passive electronic component could endanger human life or health (e.g. in accident preventi on, life-saving systems, or automotive battery line applications such as clamp 30), ensure by suitable design of the application or other measures (e.g. installation of protective ci rcuitry or redundancy) that no injury or damage is sustained by third parties in the event of such a malfunction or failure. only use ctvs components from the auto series in safety-relevant applications.
ceramic transient voltag e suppressors b72510h1140s272 smd multilayer varistor for high temp erature application CN0805S14BAUTOHTG2 kb vs pe 2009-07-16 please read cautions and warnings and page 9 of 12 important notes at the end of this document . ? specified values only apply to ctvs components that have not been subject to prior electrical, mechanical or thermal damage. the use of ctvs devices in line-to-ground applications is therefore not advisable, and it is only allowed together with safety countermeasures like thermal fuses. storage ? only store ctvs in their original packaging. do not open the package before storage. ? storage conditions in original packaging: temperature ? 25 to +45c, relative humidity 75% annual average, maximum 95%, dew precipitation is inadmissible. ? do not store ctvs devices where they are exposed to heat or direct sunlight. otherwise the packaging material may be deformed or ctvs may stick together, causing problems during mounting. ? avoid contamination of the ctvs surface during storage, handling and processing. ? avoid storing ctvs devices in harmful environm ents where they are exposed to corrosive gases for example (so x , cl). ? use ctvs as soon as possible after opening factor y seals such as polyvinyl-sealed packages. ? solder ctvs components after shipment from epcos within the time specified: o ctvs with ni barrier termination, 12 months o ctvs with agpd/agpt termination, 6 months o shcv and cu series, 24 months handling ? do not drop ctvs components and allow them to be chipped. ? do not touch ctvs with your bare hands - gloves are recommended. ? avoid contamination of the ctvs surface during handling. mounting ? when ctvs devices are encapsulated with seal ing material or overmolded with plastic material, be sure to observe the precautions in ?mounting instructions?, ?sealing, potting and overmolding?. ? make sure an electrode is not scratched before, during or after the mounting process. ? make sure contacts and housings used for assembly with ctvs components are clean before mounting.
