• 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.
• Please be aware that Products provided in bulk packaging may get bent and might lead to derivations from the mechanical
manufacturing tolerances mentioned in chapter A, which is not considered to be a material defect.
Handling:
Soldering:
• Violation of the technical product specifications such as exceeding the nominal rated voltage will void the warranty.
• The varistor is not designed for voltage stabilization with continuous power dissipation.
• The exposure of steam, saline spray, atmosphere with reduced oxygen content, corrosive gases, rain or condensation and direct sunlight
shall be prohibited.
• Signals operated continuously with a high ratio of direct-current voltage might have an influence on the product lifetime.
• 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.
• 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.
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:
Cleaning and Washing:
• Washing agents used during the production to clean the customer application might damage or change the characteristics of the
coating 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 component body, pins or termination. Expansion could damage the
components. We recommend a manual inspection after potting to avoid these effects.

Important Notes
6. Product Life Cycle
The following conditions apply to all goods within the product range of Würth Elektronik
eiSos GmbH & Co. KG:
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.
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.
2. Customer Responsibility related to Specific, in particular Safety-Relevant Applications
It has to be clearly pointed out that the possibility of a malfunction of electronic components or failure before the end of the usual lifetime
cannot be completely eliminated in the current state of the art, even if the products are operated within the range of the specifications.
In certain customer applications requiring a very high level of safety and especially in customer applications in which the malfunction or
failure of an electronic component could endanger human life or health it must be ensured by most advanced technological aid of suitable
design of the customer application that no injury or damage is caused to third parties in the event of malfunction or failure of an electronic
component. Therefore, customer is cautioned to verify that data sheets are current before placing orders. The current data sheets can be
downloaded at www.we-online.com.
