Material Compliance

RoHS, REACh & Halogen Free

Würth Elektronik eiSos is committed to the manufacture of environmentally friendly products. We are working to achieve this by eliminating lead and other hazardous substances. This complies with the directives of the European Union, other international regulations and the "Green Procurement" guidelines of our customers.

Here you will find the most important information about RoHS, REACh and Halogen Free.

RoHS Conformity

As one of the first manufacturers to do so, we have consistently taken up the topic and converted our manufacturing process exclusively to the fulfilment of meaningful environmental standards. For more than 14 years now, we have not manufactured any products that do not comply with the current and next RoHS directives (Restriction of the Use of certain Hazardous Substances in Electrical and Electronic Equipment) of the European Union (EU). This directive prohibits the use of certain substances in electrical and electronic equipment as of July 2006.

The most important contents of the RoHS Directive are as follows

Equipment placed on the market after 01.07.2006 may no longer exceed the following limit values for certain materials:

  • Lead (0.1%)
  • Mercury (0.1%)
  • Cadmium (0.1%)
  • Hexavalent chromium (0.1%)
  • Polybrominated biphenols or polybrominated diphenyl ethers (0.1%)

Exemptions

  • Lead in copper alloys (e.g. brass) up to a mass fraction of 4%. This includes the power supply elements from Würth Elektronik.
  • High temperature solders with a lead content of more than 85%. This includes the LAN and LAN RJ45 transformers from Würth Elektronik.

The conversion of production to RoHS components at Würth Elektronik was on 01.10.2004. Since then, all products can only be ordered in RoHS-compliant versions. In general, however, all lead-free components can still be soldered containing lead.

WEEE Directive

In accordance with the EU Directive 2012/19/EU of the European Union on Waste Electrical and Electronic Equipment (WEEE) and the Act on the Placing on the Market, Return and Environmentally Compatible Disposal of Electrical and Electronic Equipment (Elektro- und Elektronikgerätegesetz - ElektroG), Würth Elektronik eiSos labels its products that are subject to the directive/law with the symbol of a crossed-out wheeled bin in accordance with the EN 50419 standard.

REACh conformity

In addition to RoHS, compliance with the current ECHA directives is also an important concern for us. We see it as our responsibility to comply with these directives and not to use restricted substances and chemicals. According to Article 33, Paragraph 1 of the European REACh Regulation No. 1907/2006, we are obliged to inform about the contents of the listed substances in our products and articles.

A team is continuously working on the early identification of new substances and timely compliance with the directive. Through continuous repeat testing by our accredited partners, we can confirm the conformity of our products at any time and are always meaningful to these. We also ask our suppliers at regular intervals whether and to what extent other of the listed substances are contained in the goods to be delivered to us.

Halogen Free

As one of the leading manufacturers of electronic components, the Würth Elektronik eiSos Group is aware of its responsibility towards the environment and health. Therefore, hazardous or potentially harmful substances are controlled and tested by external test laboratories. Halogen Free" takes special care in addition to existing directives and regulations such as RoHS and REACh. A distinction must be made between halogenides (halogen ions) and halogen-containing polymers such as PVC, chlorinated flame retardants (CFR) and brominated flame retardants (BFR). In contrast to halides, which generally do not pose a health risk, PVC/CFR/BFR do under certain circumstances.

Würth Elektronik eiSos defines the limits of the halogen content by the amount of halogens from the sources PVC, CFR and BFR. Every electronic component marked as "Halogen Free" by Würth Elektronik eiSos meets one of the following requirements. The analysis always refers to the individual subcomponents of the component (homogeneous material).
