General Some parts of this publication contain statements about the suitability of our CeraCharge components for certain areas of application, including recommendations about incorporation/design-in of these products into customer applications. The statements are based on our knowledge of typical requirements often made of our CeraCharge devices in the particular areas. We nevertheless expressly point out that such statements cannot be regarded as binding statements about the suitability of our CeraCharge components for a particular customer application. As a rule, TDK Electronics is either unfamiliar with individual customer applications or less familiar with them than the customers themselves. For these reasons, it is always incumbent on the customer to check and decide whether the CeraCharge devices with the properties described in the product specification are suitable for use in a particular customer application.  Do not use CeraCharge components for purposes not identified in our specifications.  Ensure the suitability of a CeraCharge in particular by testing it for reliability during design-in.  Always evaluate a CeraCharge component under worst-case application conditions.  Pay special attention to the reliability of CeraCharge devices intended for use in safety-critical applications (e.g. medical equipment, automotive).  CeraCharge component is recommended to use below 60% of relative humidity condition.  Please take care to use each CeraCharge component within the voltage range of the specified value when using multiple in parallel and series.  Please note that charging the battery leads to a volume change of the active material due to the electrochemical reactions therein. The volume change may lead to a stress relief procedure.  Polarity will be applied with the first charging.  Nominal capacity will be observed after a few (typically more than three) cycles of charge and discharge. Design notes  In some cases the malfunctioning of 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 an electronic component could endanger human life or health (e.g. in accident prevention, life-saving systems), ensure by suitable design of the application or other measures that no injury or damage is sustained by third parties in the event of such a malfunction or failure.  Specified values only apply to CeraCharge components that have not been subject to prior electrical, mechanical or thermal damage.

Do not open the package prior to processing.  Storage conditions in original packaging: temperature -25 to +45 °C, relative humidity ≤ 75% annual average, dew precipitation is inadmissible.  Do not store CeraCharge components where they are exposed to heat or direct sunlight. Otherwise the packaging material may be deformed or CeraCharge may stick together, causing problems during mounting.  Avoid contamination of the CeraCharge surface during storage, handling and processing.  Avoid storing CeraCharge components in harmful environments where they are exposed to corrosive gases (e.g. Hydrogen Sulphide, Hydrogen Sulphate, Chlorine, Ammonia and Sulfur).  Use CeraCharge as soon as possible after opening factory seals such as polyvinyl-sealed packages.  Solder CeraCharge components after shipment from TDK Electronics within 3 months. After opening the package, solder CeraCharge components within 1 week. Handling     Do not drop CeraCharge components and allow them to be chipped. Do not touch CeraCharge components with your bare hands - gloves are recommended. Avoid contamination of the CeraCharge surface during handling. Washing processes may damage the product due to the possible static or cyclic mechanical loads (e.g. ultrasonic cleaning). They may cause cracks to develop on the product and its parts, which might lead to reduced reliability or lifetime. Mounting  When CeraCharge components are encapsulated with sealing material or overmolded with plastic material, prevent any mechanical clamping of the components.  Make sure any electrode is not scratched before, during or after the mounting process.  Make sure contacts and housings used for assembly with CeraCharge components are clean before mounting.  Avoid contamination of the CeraCharge surface during processing.  The P.C. board which has CeraCharge components shall not be bended more than 1 mm. Soldering  Complete removal of flux is recommended to avoid surface contamination that can result in an instable and/or high leakage current.  Use resin-type or non-activated flux.  Bear in mind that insufficient preheating may cause ceramic cracks.  Rapid cooling by dipping in solvent is not recommended, otherwise a component may crack. Operation  Use CeraCharge only within the specified operating temperature range and recommended relative humidity condition.  Use CeraCharge only within specified voltage and current ranges.

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 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, we are either unfamiliar with individual customer applications 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 a product with the properties described 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 life-saving 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 Material Data Sheets on the Internet (www.tdk-electronics.tdk.com/material). Should you have any more detailed 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 foregoing for customer-specific products. 6. Unless otherwise agreed in individual contracts, all orders are subject to our General Terms and Conditions of Supply. 7. Our manufacturing sites serving the automotive business apply the IATF 16949 standard. The IATF certifications confirm our compliance with requirements regarding the quality management system in the automotive industry. Referring to customer requirements and customer specific requirements (“CSR”) TDK always has and will continue to have the policy of respecting individual agreements. Even if IATF 16949 may appear to support the acceptance of unilateral requirements, we hereby like to emphasize that only requirements mutually agreed upon can and will be implemented in our Quality Management System. For clarification purposes we like to point out that obligations from IATF 16949 shall only become legally binding if individually agreed upon. Page 14 of 15 Important notes 8.
