Subject: Compliance with EU Directives CEL certifies, to its knowledge, that semiconductor and laser products detailed below are compliant with the requirements of European Union (EU) Directive 2002/95/EC Restriction on Use of Hazardous Substances in electrical and electronic equipment (RoHS) and the requirements of EU Directive 2003/11/EC Restriction on Penta and Octa BDE. CEL Pb-free products have the same base part number with a suffix added. The suffix -A indicates that the device is Pb-free. The -AZ suffix is used to designate devices containing Pb which are exempted from the requirement of RoHS directive (*). In all cases the devices have Pb-free terminals. All devices with these suffixes meet the requirements of the RoHS directive. This status is based on CEL's understanding of the EU Directives and knowledge of the materials that go into its products as of the date of disclosure of this information.
Restricted Substance per RoHS Lead (Pb) Mercury Cadmium Hexavalent Chromium PBB PBDE Concentration Limit per RoHS (values are not yet fixed) < 1000 PPM < 1000 PPM < 100 PPM < 1000 PPM < 1000 PPM < 1000 PPM Concentration contained in CEL devices -A Not Detected Not Detected Not Detected Not Detected Not Detected Not Detected -AZ (*)
