Chip Ferrite Bead Procurement Notes

Verify the specific suffix and packaging configuration against official Taiyo Yuden documentation before ordering. Confirm that the AEC-Q200 qualification status meets your project's automotive reliability requirements. Ensure the 1206 footprint matches your PCB design constraints. Cross-reference part number aliases such as LSMCA321611T380NG if sourcing from distributors listing previous part numbers.

Chip Ferrite Bead Selection Notes

Select this component when designing circuits requiring noise suppression on power rails carrying up to 6 A. The 38 Ohm impedance at 100 MHz targets specific high-frequency noise profiles. The low DCR of 5 mOhms helps maintain efficiency in power delivery networks. Consider the 1.1 mm height profile for space-constrained automotive assemblies where standard 1.6 mm beads may not fit.

Chip Ferrite Bead Part Context

This part belongs to the FB series M type, specifically engineered as a chip bead inductor for power lines. Taiyo Yuden produces these components under TS-16949 certified factory standards. The product line focuses on providing reliable EMI suppression solutions for demanding environments, particularly within the automotive sector where thermal stability and current capacity are critical performance factors.
