BLM18BB750SH1D

Chip Ferrite Bead Overview

The Murata BLM18BB750SH1D is a single-line ferrite bead in the EMIFIL BLM18 series, housed in a 0603 (1608 metric) surface-mount package. It provides an impedance of 75 Ohms at a test frequency of 100 MHz with a tolerance of 25%. The component supports a maximum DC current of 300 mA and has a maximum DC resistance of 700 mOhms. It operates within a temperature range of -55°C to +125°C and meets AEC-Q200 automotive qualification standards.

Chip Ferrite Bead Feature Summary

• Provides high-frequency noise suppression through resistive loss characteristics in the RF spectrum.
• Designed for compact circuit layouts using standard 0603 surface-mount packaging.
• Qualified for automotive applications under AEC-Q200 reliability standards.

Chip Ferrite Bead Applications

• High-speed digital signal line filtering in automotive electronic control units.
• Power supply noise attenuation on data buses requiring low DC resistance.
• EMI suppression in compact mobile device power distribution networks.

Chip Ferrite Bead Procurement Notes

Verify the suffix SH1D against SZ1D or other variants to ensure correct impedance and current ratings. Confirm RoHS3 compliance status for specific regional regulatory requirements. Check manufacturer datasheets for updated moisture sensitivity levels and recommended reflow soldering profiles prior to assembly integration.

Chip Ferrite Bead Selection Notes

Select this component when a 75 Ohm impedance at 100 MHz is required for single-line differential mode filtering. Ensure the 300 mA current rating exceeds the peak operating current of the target circuit. The 0603 footprint must align with existing PCB land patterns. Verify thermal performance under continuous DC load conditions.

Chip Ferrite Bead Part Context

This part belongs to the Murata EMIFIL BLM18 family of chip ferrite beads. The series offers various impedance values and current ratings within the 0603 package size. It serves as a passive EMI suppression solution for modern electronics requiring small form factors and reliable noise attenuation across wide frequency bands.

Chip Ferrite Bead Replacement Considerations

BLM18BA750SZ1D shares the same impedance and package but may differ in current handling or tolerance specifications. Cross-reference official Murata documentation to confirm electrical equivalence before substitution.
