Packaging:  
Würth Elektronik must be asked for written approval (following the PPAP procedure) before incorporating the components into any  
equipment in fields such as military, aerospace, aviation, nuclear control, submarine, transportation (automotive control, train control,  
ship control), transportation signal, disaster prevention, medical, public information network, etc. where higher safety and reliability are  
especially required and/or if there is the possibility of direct damage or human injury.  
•
The packaging specifications apply only to purchase orders comprising whole packaging units. If the ordered quantity exceeds or is  
lower than the specified packaging unit, packaging in accordance with the packaging specifications cannot be ensured.  
•
•
Electronic components that will be used in safety-critical or high-reliability applications, should be pre-evaluated by the customer.  
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 component may be damaged or dissolved.  
Handling:  
•
•
Do not drop or impact the components, the component may be damaged.  
•
•
Violation of the technical product specifications such as exceeding the nominal rated current will void the warranty.  
Würth Elektronik products are qualified according to international standards, which are listed in each product reliability report. Würth  
Elektronik does not warrant any customer qualified product characteristics beyond Würth Elektroniks’ specifications, for its validity and  
sustainability over time.  
The responsibility for the applicability of the customer specific products and use in a particular customer design is always within the  
authority of the customer. All technical specifications for standard products also apply to customer specific products.  
The temperature rise of the component must be taken into consideration. The operating temperature is comprised of ambient  
temperature and temperature rise of the component.The operating temperature of the component shall not exceed the maximum  
temperature specified.  
•
These cautions and warnings comply with the state of the scientific and technical knowledge and are believed to be accurate and reliable.  
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. Wave soldering is  
allowed for components bigger than 0802 after evaluation and approval.  
All other soldering methods are at the customers’ own risk.  
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.  
Potting:  
•
If the product is potted in the customer application, the potting material might shrink or expand during and after hardening. Shrinking  
could lead to an incomplete seal, allowing contaminants into the core. Expansion could damage the components. We recommend a  
manual inspection after potting to avoid these effects.

6. Product Life Cycle  
Important Notes  
Due to technical progress and economical evaluation we also reserve the right to discontinue production and delivery of products. As a  
standard reporting procedure of the Product Termination Notification (PTN) according to the JEDEC-Standard we will inform at an early stage  
about inevitable product discontinuance. According to this we cannot guarantee that all products within our product range will always be  
available. Therefore it needs to be verified with the field sales engineer or the internal sales person in charge about the current product  
availability expectancy before or when the product for application design-in disposal is considered. The approach named above does not  
apply in the case of individual agreements deviating from the foregoing for customer-specific products.  
The following conditions apply to all goods within the product range of Würth Elektronik  
eiSos GmbH & Co. KG:  
1. General Customer Responsibility  
Some goods within the product range of Würth Elektronik eiSos GmbH & Co. KG contain statements regarding general suitability for certain  
application areas. These statements about suitability are based on our knowledge and experience of typical requirements concerning the  
areas, serve as general guidance and cannot be estimated as binding statements about the suitability for a customer application. The  
responsibility for the applicability and use in a particular customer design is always solely within the authority of the customer. Due to this  
fact it is up to the customer to evaluate, where appropriate to investigate and decide whether the device with the specific product  
characteristics described in the product specification is valid and suitable for the respective customer application or not.  
7. Property Rights  
All the rights for contractual products produced by Würth Elektronik eiSos GmbH & Co. KG on the basis of ideas, development contracts as  
well as models or templates that are subject to copyright, patent or commercial protection supplied to the customer will remain with Würth  
Elektronik eiSos GmbH & Co. KG. Würth Elektronik eiSos GmbH & Co. KG does not warrant or represent that any license, either expressed or  
implied, is granted under any patent right, copyright, mask work right, or other intellectual property right relating to any combination,
