Array (BGA). Devices that are lead-free are
marked with a circled “e1” and have a
product code: NHXXXXX
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 Hazard-
ous Substances (RoHS) -banned materials, is available at:
