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

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.
Cautions and Warnings:
The following conditions apply to all goods within the product series of WE-PD2 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.
• The component was 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, as the core may flake apart.
• 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 customer is responsible for the functionality of their own products. All technical specifications for standard products also apply to
customer specific products.
Potting:
• If the product is potted in the costumer application, the potting material may shrink or expand during and after hardening. Shrinking
could lead to an incomplete seal, allowing contaminants into the core. Expansion could damage the core or wire contacts. We
recommend a manual inspection after potting to avoid these effects.
Storage Conditions:
• A storage of Würth Electronik 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.
• The storage conditions stated in the original packaging apply to the storage time and not to the transportation time of the components.
Handling:
• Violation of the technical product specifications such as exceeding the nominal rated current will void the warranty.
• Applying currents with audio-frequency signals may result in audible noise due to the magnetostrictive material properties.
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 Würth Elektronik technical soldering specification. 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 may 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 could break the wire due to its small diameter. Therefore, we do not recommend using a
brush during the PCB cleaning process.
