Ordering and Marking Information
Note:
lead-free products contain molding compounds/die attach materials and 100%matte tin plate termination finish;which are fully compliant with RoHS.lead-free products meet or exceed the lead-fr
ee requirements of IPC/JEDEC J -STD-020D for MSL classification at lead-free peak reflow temperature.defines “Green”to mean lead-free (RoHS compliant)and halogen free (Br or Cl does not exceed 900ppm by weight in homogeneous material and total of Br and Cl does not exceed 1500ppm by weight).
