< Semtech – REACH-SVHC 205 Compliance Inquiry >

Dear Valued Customer, March 19, 2020

Semtech Corporation acknowledges that the European Union has enacted the “REACH Regulation”,

EC1907/2006. And within that regulation, Annex XIV addresses a listing of Substances of Very High

Concern, SVHC, and Annex XVII which maintains a complete listing of hazardous substances along

with restrictions on the manufacture and release to market of such hazardous substances.

As Annex XIV continues to mature addressing SVHC candidate list of substances proposed by ECHA

(European Chemical Agency), and the guidelines defining protocol for the semiconductor industry are

ratified, Semtech Corporation will continue to assess impact to our product, and the manufacturing

processes used by our suppliers, and continue to take appropriate actions necessary to ensure

compliance while maintaining the integrity of our supply chain.

As of the date of this letter, Semtech product, identified as pb-free, RoHS compliant, and their related

processes do not intentionally use, add, contain nor exceed 0.1% weight by weight, or release any

of the substances of very high concern listed in annex XIV and referenced in the attached table.

This also applies to the Semtech product noted below which you expressed an interest in.

Part number(s): SX1231IMLTRT

Additionally, Semtech Corporation employs and maintains a fabless business model as we, do not,

own any significant portion of a fabrication or assembly process.

Pursuant to our business model, Semtech Corporation does not own nor operate a fabrication facility

within the European Union. In that regard, we do not order, maintain nor dispose of chemicals at the

levels specified by the European regulation governing REACH reporting and compliance. The quantities

and weights of Semtech components shipped into other countries are well below the minimum weight

guidelines specified in the regulation.

As a result, Semtech Corporation believes that the guidelines governing REACH registration,

evaluation, and authorization are not applicable to the scope of manufacturing and shipment of

Semtech product.

Semtech Corporation will re-evaluate its reporting and compliance requirements as the regulation is

revised, or significant changes in industry guidelines are imposed.

Semtech Corporation “Thanks You” for your inquiry and looks forward to a continued and successful

business relationship.

If you have any questions, do not hesitate to give me a call.
