Procurement Notes

Verify the specific suffix codes against official Murata documentation to ensure correct impedance and packaging specifications. Confirm RoHS compliance status through the manufacturer's latest datasheet or certification documents before integration into regulated products.

Selection Notes

Select this component when a 31 Ohm impedance at 1 MHz is required for high-frequency noise attenuation. Ensure the circuit design accommodates the 2 A maximum DC current rating and verify that the 2020 package dimensions fit the available PCB real estate constraints.

Part Context

This ferrite bead belongs to the NFZ series, which consists of impedance components optimized for suppressing electromagnetic interference in the VHF band. The series offers various impedance values and current ratings within standardized SMD packages to support diverse EMI mitigation strategies in modern electronics.

Replacement Considerations

Check for direct substitutes within the NFZ series offering identical 31 Ohm impedance and 2020 package dimensions. Verify equivalent current ratings and thermal characteristics before substituting with other manufacturers' ferrite beads.
