Procurement Notes
Verify the specific suffix against official datasheets, as variations may exist between tape-and-reel and cut-tape formats. Confirm RoHS compliance status and moisture sensitivity level prior to assembly. Ensure the ordering code matches the required packaging quantity and lead time requirements for production schedules.
Selection Notes
Select this component when space constraints require a 0402 footprint for high-frequency noise attenuation. Evaluate the 350mA current rating against peak load conditions to prevent saturation. Consider the 47 Ohm impedance value relative to the target noise frequency spectrum for effective suppression performance.
Part Context
This part belongs to the BK series of multilayer chip bead inductors. It serves as a passive component for electromagnetic interference reduction. The product line emphasizes miniaturization while maintaining electrical stability across wide temperature ranges for industrial and automotive use cases.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with alternative ferrite beads by matching impedance curves, current ratings, and physical dimensions before substitution.
