BLM18BB750SN1D

Chip Ferrite Bead Overview

The BLM18BB750SN1D is a single-line ferrite bead from the Murata EMIFIL BLM18BB series, designed for surface-mount applications in the 0603 (1608 metric) 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 500 mA and features a maximum DC resistance of 250 mOhms. It operates within a temperature range of -55°C to +125°C.

Chip Ferrite Bead Feature Summary

• Provides high-impedance attenuation for common-mode noise suppression on single signal lines
• Compact 0603 surface-mount footprint suitable for space-constrained PCB layouts
• Capable of handling rated DC currents without significant performance degradation

Chip Ferrite Bead Applications

• EMI suppression filters for high-speed digital signal lines
• Noise filtering in portable electronic devices
• Power line conditioning for sensitive integrated circuits

Chip Ferrite Bead Procurement Notes

Verify the complete part number including suffixes such as SN1D to ensure correct packaging and impedance specifications. Confirm RoHS3 compliance status and moisture sensitivity level requirements prior to integration into the manufacturing process. Cross-reference official datasheets for specific handling instructions.

Chip Ferrite Bead Selection Notes

Select this component when a 75 Ohm impedance at 100 MHz is required for a single-line application. Ensure the 500 mA current rating meets the circuit's operational demands. The 0603 package size must align with the available board space and automated placement capabilities.

Chip Ferrite Bead Part Context

This component belongs to the Murata BLM18BB series of chip ferrite beads. It shares the same physical dimensions and general characteristics as other variants in the series but differs in impedance values and current ratings. It is distinct from the BLM18BA series which typically offers higher resistance values.

Chip Ferrite Bead Replacement Considerations

Direct substitutes include BLM18BB750SZ1D and BLM18BA750SN1D. Verify that alternative parts match the required impedance, current rating, and package dimensions before implementation.
