Cautions and Warnings: Potting: • If the product is potted in the customer application, the potting material might shrink or expand during and after hardening. Shrinking The following conditions apply to all goods within the product series of WE-LQ of Würth could lead to an incomplete seal, allowing contaminants into the core. Expansion could damage the component. We recommend a Elektronik eiSos GmbH & Co. KG: manual inspection after potting to avoid these effects. General: Storage Conditions: • This electronic component is designed and manufactured for use in general electronic equipment. • A storage of Würth Elektronik products for longer than 12 months is not recommended. Within other effects, the terminals may suffer • Würth Elektronik must be asked for written approval (following the PPAP procedure) before incorporating the components into any degradation, resulting in bad solderability. Therefore, all products shall be used within the period of 12 months based on the day of equipment in fields such as military, aerospace, aviation, nuclear control, submarine, transportation (automotive control, train control, shipment. ship control), transportation signal, disaster prevention, medical, public information network etc. where higher safety and reliability are • Do not expose the components to direct sunlight. especially required and/or if there is the possibility of direct damage or human injury. • The storage conditions in the original packaging are defined according to DIN EN 61760-2. • Electronic components that will be used in safety-critical or high-reliability applications, should be pre-evaluated by the customer. • The storage conditions stated in the original packaging apply to the storage time and not to the transportation time of the components. • The component is designed and manufactured to be used within the datasheet specified values. If the usage and operation conditions specified in the datasheet are not met, the wire insulation may be damaged or dissolved. Handling: • Do not drop or impact the components, the component may be damaged. • Würth Elektronik products are qualified according to international standards, which are listed in each product reliability report. Würth • Violation of the technical product specifications such as exceeding the nominal rated current will void the warranty. Elektronik does not warrant any customer qualified product characteristics beyond Würth Elektroniks’ specifications, for its validity and • Applying currents with audio-frequency signals may result in audible noise due to the magnetostrictive material properties. sustainability over time. • The responsibility for the applicability of the customer specific products and use in a particular customer design is always within the These cautions and warnings comply with the state of the scientific and technical knowledge and are believed to be accurate and reliable. authority of the customer. All technical specifications for standard products also apply to customer specific products. However, no responsibility is assumed for inaccuracies or incompleteness. Product specific: Soldering: • The solder profile must comply with the technical product specifications. All other profiles will void the warranty. • All other soldering methods are at the customers’ own risk. • Strong forces which may affect the coplanarity of the components’ electrical connection with the PCB (i.e. pins), can damage the part, resulting in avoid of the warranty. Cleaning and Washing: • Washing agents used during the production to clean the customer application might damage or change the characteristics of the wire insulation, marking or plating. Washing agents may have a negative effect on the long-term functionality of the product. • Using a brush during the cleaning process may break the wire due to its small diameter. Therefore, we do not recommend using a brush during the PCB cleaning process.
