• Surface mount construction suitable for automated assembly

Chip Ferrite Bead Applications

• Signal line filtering
• EMI suppression filters
• High-speed signal lines

Chip Ferrite Bead Procurement Notes

Verify the specific part number against official Murata documentation to confirm electrical ratings. Datasheets indicate a 150 mA rating and 1.5 Ω DC resistance. Cross-reference distributor listings carefully, as some sources may list conflicting current values or impedance tolerances. Ensure the ordering suffix matches the required packaging format.

Chip Ferrite Bead Selection Notes

Select this component for applications requiring high impedance attenuation at 100 MHz within a compact 0603 footprint. The 150 mA current rating limits suitability for power lines; it is intended for signal integrity management. Verify that the 1.5 Ω DC resistance does not introduce excessive voltage drop in the target circuit design.

Chip Ferrite Bead Part Context

This component belongs to the Murata BLM18 series of chip ferrite beads. The series utilizes ferrite material to suppress electromagnetic interference. The BLM18BD variant specifically denotes the impedance characteristics and package type within the broader family of surface-mount noise suppression components manufactured by Murata Electronics.

Chip Ferrite Bead Replacement Considerations

Direct substitutes include other Murata BLM18 series parts with matching 2200 Ω impedance at 100 MHz, such as BLM18BD221SN1D if lower impedance is acceptable. Verify physical dimensions and terminal compatibility before substitution.
