Chip Ferrite Bead Procurement Notes

Verify the complete part number against official Murata documentation to ensure correct impedance and current ratings. Confirm RoHS compliance status and moisture sensitivity level requirements for your specific manufacturing process. Check for any specific packaging preferences such as cut tape or reel quantities during ordering.

Chip Ferrite Bead Selection Notes

Select this component when a 150 Ohm impedance at 100 MHz is required within a compact 0603 footprint. Ensure the circuit's DC current does not exceed 1.4 A to prevent saturation. Consider the low DC resistance of 120 mOhms for minimal voltage drop in power-sensitive applications.

Chip Ferrite Bead Part Context

This component belongs to the Murata EMIFIL BLM18DN series of ferrite beads. These parts are engineered for general-purpose EMI suppression in portable devices and industrial electronics. The series offers various impedance values while maintaining consistent physical dimensions for design flexibility.

Chip Ferrite Bead Replacement Considerations

Consult official Murata substitution guides for compatible alternatives. Verify that any substitute matches the 150 Ohm impedance, 1.4 A current rating, and 0603 package dimensions to ensure mechanical and electrical compatibility.
