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.
Cautions and Warnings:
The following conditions apply to all goods within the product series of WE-LQS 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 a written approval (following the certain PPAP level procedure) before incorporating the components
into any equipment in the field 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 possibility of direct damage or injury to human body.
• In addition, even electronic components in general electronic equipment require a sufficient reliability evaluation-check for the safety,
when used in electrical circuits that require high safety, reliability functions or performance, prior to usage.
• The electronic component is designed and manufactured to be used within the datasheets’ specified values. The usage and operation of
the product within ambient conditions, which probably dissolve or harm the wire isolation, has to be avoided.
• The responsibility for the function of the application of the customer specific products and use in a particular customer design is always
the full and autonomous responsibility of the customer. All technical specification for standard products also apply to customer specific
products.
• Direct mechanical impact to the product shall be prevented as the ferrite material of the core could flake or in the worst case it could
break.
• 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 characteristic, beyond Würth Elektronik specifications, for its validity and
sustainability over time.
• Limiting factors for the storage stability of electronic components are material characteristics and a solderability decrease of the
terminations. Therefore all products shall be used within the period of 12 month based on the day of shipment.
• Do not expose the components into direct sunlight.
• The storage condition in the original packaging refered to DIN EN 61760-2.
Potting:
• If the product is potted in the costumer applications, the potting material might shrink during and after hardening. The product is
exposed to the pressure of the potting material with the effect that the core, wire and termination is possibly damaged by this pressure
and so the electrical as well as the mechanical characteristics are endangered to be affected. After the potting material is cured, the
core, wire and termination of the product require the inspection for any reduced electrical or mechanical functions or potential
destructions.
Handling:
• Violation of the technical product specifications such as exceeding the nominal rated current will void the warranty.
• The general and product specific cautions 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, 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 wire
insulation, the marking or the plating. The washing agent could have a negative effect on the long term functionality of the product.
