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.
I Cautions and Warnings:
The following conditions apply to all goods within the product series of WE-FLAT
of Würth Elektronik eiSos GmbH & Co. KG:
General:
All recommendations according to the general technical specifications of the data sheet have to be complied with.
The usage and operation of the product within ambient conditions, which probably alloy or harm the component surface, has to be avoided.
If the product is molded in costumer applications, the molding material might shrink during and after hardening. The product is exposed to the
pressure of the molding material with the effect that the ferrite body is possibly damaged by this pressure and so the electrical as well as the
mechanical characteristics are endangered to be affected. After the molding material is cured, the ferrite body of the product have to be
checked if any reduced electrical or mechanical functions or destructions have occurred.
The responsibility for the applicability of customer specific products and use in a particular customer design is always within the authority of
the customer. All technical specifications for standard products do also apply to customer specific products.
Cleaning agents that are used to clean the customer application might damage or change the characteristics of the component or body.
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 at
the characteristics of the material. The acidly or salted environment could have a negative effect on the long turn function of the product.
Direct mechanical impact to the product shall be prevented as the ferrite material of the ferrite body could flake or in the worst case it could
break.
Product specific:
Follow all instructions mentioned in the data sheet, especially:
•Violation of the technical product specifications such as exceeding the maximal outer diameter of the cable 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.

J 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 are-
as, serve as general guidance and cannot be estimated as binding statements about the suitability for a customer application. The responsibi-
lity 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.
2. Customer Responsibility related to Specific, in particular Safety-Relevant Applications
It has to be clearly pointed out that the possibility of a malfunction of electronic components or failure before the end of the usual lifetime can-
not be completely eliminated in the current state of the art, even if the products are operated within the range of the specifications.
In certain customer applications requiring a very high level of safety and especially in customer applications in which the malfunction or failure
of an electronic component could endanger human life or health it must be ensured by most advanced technological aid of suitable design of
the customer application that no injury or damage is caused to third parties in the event of malfunction or failure of an electronic component.
Therefore, customer is cautioned to verify that data sheets are current before placing orders. The current data sheets can be downloaded at
www.we-online.com.
3. Best Care and Attention
Any product-specific notes, cautions and warnings must be strictly observed. Any disregard will result in the loss of warranty.
4. Customer Support for Product Specifications
Some products within the product range may contain substances which are subject to restrictions in certain jurisdictions in order to serve spe-
cific technical requirements. Necessary information is available on request. In this case the field sales engineer or the internal sales person in
charge should be contacted who will be happy to support in this matter.
5. Product R&D
Due to constant product improvement product specifications may change from time to time. As a standard reporting procedure of the Product
Change Notification (PCN) according to the JEDEC-Standard inform about minor and major changes. In case of further queries regarding the
PCN, the field sales engineer or the internal sales person in charge should be contacted. The basic responsibility of the customer as per Secti-
on 1 and 2 remains unaffected.
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 stan-
dard 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 ex-
pectancy 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.
7. Property Rights
All the rights for contractual products produced by Würth Elektronik eiSos GmbH & Co. KG on the basis of ideas, development contracts as
well as models or templates that are subject to copyright, patent or commercial protection supplied to the customer will remain with Würth
Elektronik eiSos GmbH & Co. KG.
Würth Elektronik eiSos GmbH & Co. KG does not warrant or represent that any license, either expressed or implied, is granted under any pa-
tent right, copyright, mask work right, or other intellectual property right relating to any combination, application, or process in which Würth
Elektronik eiSos GmbH & Co. KG components or services are used.
8. General Terms and Conditions
Unless otherwise agreed in individual contracts, all orders are subject to the current version of the “General Terms and Conditions of Würth
Elektronik eiSos Group”, last version available at www.we-online.com.
