Allegro Adds Materials Declaration Reports to the Web

July 6, 2006

In order to comply with the EU RoHS and Waste Electrical and Electronic Equipment (WEEE) directives of supplying materials declaration reports to end product users, Allegro has created reports for most devices currently posted on the web.  We want to provide our customers with detailed reports, ensuring that products do not contain banned/restricted materials.  Customers are also concerned about the presence of other materials for recyclability, sustainability targets/goals and green marketing.

On allegromicro.com, at the bottom of each product page, in the table of part numbers, a column will be added, linking to the part composition/RoHS reports.

See http://www.allegromicro.com/sf/1140/ for example.

Part Number     Package Type    Part Composition/ RoHS Data     Temperature     Comments        Samples        
A1140ELHLT      3-lead SOT      view data       -40°C to 85°C   last-time buy   samples not available  

Please provide us with your feedback and let us know if you have any questions.
Thank you.
