Procurement Notes

Verify the specific suffix SMST against the manufacturer's latest documentation to confirm packaging format and availability status. Ensure the selected variant matches the required impedance tolerance and current rating for the target application. Cross-reference the part number with official distributor catalogs to confirm active lifecycle status and compliance certifications prior to final procurement decisions.

Selection Notes

Select this component when a 430-ohm impedance at 100 MHz is required for EMI suppression. Evaluate the 700 mA current handling capability against the circuit's operational load to prevent saturation. Consider the 0603 package dimensions for space-constrained layouts. Compare the 170 milliohm DC resistance impact on voltage drop relative to other available ferrite beads in the same series.
