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.
