Cautions and Warnings:

The following conditions apply to all goods within the product series of WE-FNCS of

Würth Elektronik eiSos GmbH & Co. KG:

General:

• This electronic component was designed and manufactured for use in general electronic equipment.

• 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.

• Electronic components that will be used in safety-critical or high-reliability applications, should be pre-evaluated by the customer.

• This component is designed and manufactured for operation within the limits specified in its datasheet. Operation outside these

specified conditions may result in damage to the component and degraded performance.

• Do not drop or impact the component, the component may be damaged.

• Würth Elektronik products are qualified according to international standards, which are listed in each product reliability report. Würth

Elektronik does not guarantee 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.

Product specific:

Cleaning and Washing:

• Washing agents used during the production to clean the customer application might damage or change the characteristics of the

component, 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. Expansion could damage the component. We recommend

a manual inspection after potting to avoid these effects.

Storage Conditions:

• A storage of Würth Elektronik products for longer than 12 months is not recommended. Therefore, all products shall be used within the

period of 12 months based on the day of shipment.

• Do not expose the components to direct sunlight.

• The storage conditions in the original packaging are defined according to DIN EN 61760-2.

• The storage conditions stated in the original packaging apply to the storage time and not to the transportation time of the components.

Packaging:

• 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.

Handling:

• Care must be taken when cutting, bending or pulling the components, as small particles may come off and cracks can be created.

• For optimum adhesion properties the surface where the WE-FNCS will be placed and must be clean and dry.

• This product is classified as a laminate or compound material, mechanical stress or improper handling may lead to the release of small

conductive particles. Wherever special cleanliness or particle contamination requirements are given, please contact Würth Elektronik

technical department during the design in status. In applications where the danger of subsequent damages due to particle

contamination is given, preventive measures must be implemented by the customer.

• The temperature rise of the component must be taken into consideration. The operating temperature of the component shall not exceed

the maximum temperature specified.

• Due to the inherent characteristics of its multilayer construction, removal after application may result in partial or complete delamination

of the layers. The product is not designed to be reworkable.

• Oxidation may be promoted and performance may be reduced upon exposure to moisture, as a consequence of the presence of

nanocrystalline material.

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. V1.0
