authority of the customer. All technical specifications for standard products also apply to customer specific products.
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.
• 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.
• Due to heavy weight of the components, strong forces and high accelerations may have the effect to damage the electrical connection
or to harm the circuit board and will void the warranty.
• Please be aware that products provided in bulk packaging may get bent and might lead to derivations from the mechanical
manufacturing tolerances mentioned in our datasheet, which is not considered to be a material defect.
• 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.
• 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 component. We recommend a
manual inspection after potting to avoid these effects.

Important Notes
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.
6. Product Life Cycle
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.
