BLM15AX300SZ1D

Chip Ferrite Bead Overview

The Murata BLM15AX300SZ1D is a single-line ferrite bead in the EMIFIL BLM15 series, housed in a 0402 (1005 metric) surface-mount package. It provides an impedance of 30 Ohms at 100 MHz with a 25% tolerance. The component supports a maximum DC current of 1.1 A and exhibits a maximum DC resistance of 60 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

• Functions as a noise filter by acting as a resistor at high frequencies to reduce resonance possibilities.
• Maintains signal waveform integrity without distortion during operation.
• Automotive qualified for reliability in demanding environments.

Chip Ferrite Bead Applications

• Noise suppression in automotive electronic circuits
• High-frequency signal filtering in compact PCB designs
• Power line noise reduction in low-profile applications

Chip Ferrite Bead Procurement Notes

Verify the specific suffix 'SZ1D' against official Murata documentation to confirm packaging and tape specifications. Ensure compatibility with standard 0402 footprint dimensions and check RoHS compliance status directly from the manufacturer datasheet before integration into production workflows.

Chip Ferrite Bead Selection Notes

Select this component when a 0402 form factor is required for space-constrained layouts. The 1.1 A current rating suits moderate power lines, while the 30 Ohm impedance targets specific noise frequencies around 100 MHz. Verify thermal performance requirements against the -55°C to +125°C operating range.

Chip Ferrite Bead Part Context

This part belongs to the Murata EMIFIL BLM15 series of chip ferrite beads. The series offers various impedance values and current ratings in standardized metric packages. The BLM15AX variant specifically denotes the 0402 size with axial termination characteristics suitable for high-density mounting.

Chip Ferrite Bead Replacement Considerations

Consult official Murata substitution guides for equivalent parts. Cross-referencing requires matching impedance, current rating, and package dimensions. Generic equivalents may not meet AEC-Q200 automotive qualifications or specific frequency response curves.
