Chip Ferrite Bead Applications

• Power supply filtering
• EMI suppression filters
• High-speed signal lines

Chip Ferrite Bead Procurement Notes

Verify the specific suffix against official Murata documentation to confirm electrical characteristics, as suffixes define critical parameters like impedance and current rating. Ensure the ordering code matches the required 22-ohm specification and 6-ampere current capacity for your circuit design.

Chip Ferrite Bead Selection Notes

Select this component when high current capacity is required alongside EMI suppression in a small form factor. Compare its low DC resistance against other series to ensure minimal impact on power delivery efficiency while maintaining necessary noise attenuation at target frequencies.

Chip Ferrite Bead Part Context

This part belongs to the BLM18 series of chip ferrite beads from Murata Electronics. These components are designed for use in portable devices and industrial equipment where space is limited. The series offers various impedance and current combinations to suit different circuit requirements.

Chip Ferrite Bead Replacement Considerations

Check for direct substitutes within the BLM18 family or equivalent 0603 ferrite beads from other manufacturers that match the 22-ohm impedance and 6-ampere current ratings. Verify pin compatibility and thermal performance before substitution.
