a circled “e1” and have the product code:
compatibility
NHxxxxxx.
a. This device is lead-free. That is, lead has not been intentionally added, but lead may still exist as an impurity at <1000 ppm.
The Material Declaration Data Sheet, which includes lead impurity levels and the concentration of other Restriction on Haz-
ardous Substances (RoHS)-banned materials, is available at:

In addition, this device has been tested and conforms to the same parametric specifications as previous versions of the de-
vice. For more information regarding lead-free products from Intel Corporation, contact your Intel Field Sales representative.
