Chip Ferrite Bead Procurement Notes

Verify the specific suffix 'K' against official Eaton documentation to confirm tolerance or material specifications. Ensure the 300 mA current rating aligns with your circuit's peak load requirements. Confirm RoHS compliance status through the manufacturer's latest declaration before finalizing procurement.

Chip Ferrite Bead Selection Notes

Select this component when space constraints require a 0402 ferrite bead with moderate current handling. The 30 Ohm impedance targets specific noise frequencies around 100 MHz. Verify that the 200 mOhm DCR does not cause excessive voltage drop in low-voltage automotive circuits.

Chip Ferrite Bead Part Context

This part belongs to the Eaton MFBA3 series, which focuses on automotive-grade EMI suppression. The series utilizes multilayer technology to provide robust performance in harsh environments. It serves as a passive component for filtering high-frequency interference in vehicle electronics.

Chip Ferrite Bead Replacement Considerations

Consult Eaton's official cross-reference tools for verified substitutes. Ensure replacement parts match the 0402 footprint, 300 mA rating, and 30 Ohm impedance at 100 MHz. Automotive qualification standards must be maintained during substitution.
