Chip Ferrite Bead Procurement Notes

Verify the obsolete status of this specific part number before procurement planning. Confirm availability of direct substitutes such as LI1206H121R-10 or cross-manufacturer equivalents like BLM31PG121SN1L. Ensure that any replacement component matches the original electrical specifications and physical footprint requirements for your design.

Chip Ferrite Bead Selection Notes

Select this component for designs requiring 120 Ohm impedance at 100 MHz in a 1206 package. Consider the 800mA current rating and 150 milliohm DC resistance when evaluating voltage drop and thermal performance. Verify RoHS compliance requirements as this specific suffix may not meet current environmental standards compared to newer revisions.
