Cautions and Warnings:

The following conditions apply to all goods within the product series of wireless

connectivity of Würth Elektronik eiSos GmbH & Co. KG:

General:

• This electronic component is designed and developed with the intention 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.

• 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.

• 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

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:

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 customer’s own risk.

Cleaning and Washing:

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

component. Washing agents may have a negative effect on the long-term functionality of the product.

• Using a brush during the cleaning process could break the module. Therefore, we do not recommend using a brush during the PCB

cleaning process.

Potting and Coating:

• 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 components. We recommend a

manual inspection after potting to avoid these effects.

• Conformal coating or potting results in loss of warranty.

• The RF shield will not protect the part from low-viscosity coatings and potting. An undefined amount of coating and potting will enter

inside the shielding.

• Conformal coating and potting will influence the parts of the radio front end and consequently influence the radio performance.

• Potting will influence the temperature behaviour of the device. This might be critical for components with high power.

Storage Conditions:

• A storage of Würth Elektronik products for longer than 12 months is not recommended. Within other effects, the terminals may suffer

degradation, resulting in bad solderability. 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.

• If there is a moisture sensitive component, the storage condition in the original packaging is defined according to IPC/JEDEC-J-

STD-033. It is also recommended to return the component to the original moisture proof bag and reseal the moisture proof bag again.

• ESD prevention methods need to be followed for manual handling and processing by machinery.

• 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:

• Violation of the technical product specifications such as exceeding the nominal rated current, will void the warranty.

• Violation of the technical product specifications such as but not limited to exceeding the absolute maximum ratings will void the

conformance to regulatory requirements.

• The edge castellation is designed and made for prototyping, i.e. hand soldering purposes only.

• Non-antenna modules must be equipped with a proper antenna having specific characteristics.

• The applicable country regulations and specific environmental regulations must be observed.

• Do not disassemble the product. Evidence of tampering will void the warranty.

• 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.

All topics are described in a more detailed manner in the manual for each product.

This electronic component has been designed and developed for usage in general electronic equipment only. This product is not authorized for use in equipment where a higher safety standard and reliability standard is especially required or where a failure of the product is reasonably expected to cause severe personal injury or death, unless the parties have executed an agreement specifically governing such use. Moreover Würth Elektronik eiSos GmbH

& Co KG products are neither designed nor intended for use in areas such as military, aerospace, aviation, nuclear control, submarine, transportation (automotive control, train control, ship control), transportation signal, disaster prevention, medical, public information network etc.. Würth Elektronik eiSos GmbH & Co KG must be informed about the intent of such usage before the design-in stage. In addition, sufficient reliability evaluation checks for safety

must be performed on every electronic component which is used in electrical circuits that require high safety and reliability functions or performance.
