NOTES:
1. Please refer to TB347 for details on reel specifications.
2. These Intersil Pb-free plastic packaged products employ special Pb-free material sets: molding compounds, die attach materials, NiPdAu plate (e4
termination finish), which are all RoHS compliant. The ISL29043 is compatible with limited SnPb and Pb-free soldering operations. The ISL29043 is
MSL classified. See Tech Brief TB489 (Surface Mount Guidelines for Optical Co-packages) for reflow profile and more information.
3. For Moisture Sensitivity Level (MSL), please see device information page for ISL29043. For more information on MSL please see tech brief TB477.
