2W5:
WURTH ELEK'I'RONIK
Cautions and Warnings:
The following conditions apply to all goods within the product series of STAR-TEC of
Würth Elektronik eiSos GmbH & Co. KG:
General:
• This electronic component is 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 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 warrant 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. 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 components. 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. The material characteristics of the electronic
components create a limiting factor for the storage stability. Therefore, all products shall be used within the period of 12 months based
on the day of shipment.
• Do not expose the components into direct sunlight.
• The storage condition in the original packaging is defined according to DIN EN 61760-2.
• The packaging of the products (Moisture Impermeable Bag) is to maintain the required moisture level of the plastic housings. To ensure
this moisture level, the product either has to be stored in the original sealed packaging or needs to be stored in a humidity and
temperature controlled storage room. Otherwise, the product may lose the required moisture level and its mechanical properties. In this
case, you can re-condition the products according to the internal standard WE-Standard 1581 to ensure the required moisture level in
the plastic.
• For further information about this internal standard please refer to the document ‘WE-Standard 1581’ which can be downloaded from
the respective product page on our website.
• 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 maximum outer diameter of the cable will void the warranty.
• The usage in acidly as well as salted environment can be the reason for oxide (rust) at the surface of the ferrite body, damage or
changes to the characteristics of the material. The acidly or salted environment could have a negative effect on the long term function of
the product.
• To ensure the operating mode of the product, the ambient temperature at processing (when the part will be mounted on the cable) has
to be in the range of 15 to 35 °C. Before mounting, the part should be stored for one hour under this condition.
• 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.
