• Modified internal structure minimizes stray capacitance while maintaining effective frequency range

Chip Ferrite Bead Applications

• Automotive infotainment systems
• Power line noise filtering in vehicle electronics
• High-current signal integrity protection

Chip Ferrite Bead Procurement Notes

Verify the specific suffix SH1D against official Murata documentation to confirm packaging type and tape/reel specifications. Ensure the AEC-Q200 qualification status matches project requirements. Cross-reference the impedance value and current rating with schematic constraints before finalizing procurement orders.

Chip Ferrite Bead Selection Notes

Select this component when high current handling up to 1.2 A is required alongside significant impedance at 100 MHz. The 0603 footprint suits space-constrained designs. Verify that the 222 mOhm DC resistance meets voltage drop limits in the target power circuit. Confirm automotive grade compliance if used in vehicle systems.

Chip Ferrite Bead Part Context

This part belongs to the BLM18_H series, which utilizes a modified internal electrode structure. This design approach aims to minimize stray capacitance compared to standard ferrite beads, thereby extending the effective frequency range for noise suppression. It serves as a specialized solution for power lines where both high current capacity and broadband attenuation are necessary.

Chip Ferrite Bead Replacement Considerations

BLM18SP102SZ1D offers identical electrical parameters including 1 kOhms impedance and 1.2 A current rating but may differ in packaging or specific series characteristics. Verify functional equivalence through official datasheets before substitution.
