The less than (<) symbol is used to indicate that the test results are below the amounts indicated, which are the minimum detection limits of the laboratory performing the testing. The exception to this is for plating containing lead, where the maximum amount of lead is listed. RoHS maximum limits (ppm): 1000 for Pb, Hg, Cr6+, PBB, PBDE (exemption: lead if solderballs are used.) 100 for Cd. Reportable substances (if present): Antimony Trioxide, Brominated Flame Retardants, Nickel. Weighted average = for part as a whole. The information included herein is believed to be accurate and reliable. However, Allegro MicroSystems, Inc. assumes no responsibility for its use. The user is cautioned to verify that the information being relied upon is current.

Dear Customer:

Please note that, as a supplier of components, we are not required to assess regulatory requirements that may apply to the finished product such as the European RoHS Directive (2003/95/EC), hereinafter referred to as “RoHS”. Please note further that A3515LUA may contain small amounts of lead. Therefore, we cannot make representations, warranties or indemnities regarding the complete absence of lead in the product.

You will note that, if there is sufficient volume and the above referenced product is not below RoHS allowable thresholds, we are prepared to discuss making a product listed by Allegro that is below RoHS allowable thresholds, if that is your wish.

Allegro MicroSystems, Inc. is a cooperative environmental supplier who fully supports the global environmental initiatives. We value our relationship and we are committed to furthering our cooperation.
