BLM18BA100SZ1D

Chip Ferrite Bead Overview

The Murata BLM18BA100SZ1D is a single-line ferrite chip bead in a 0603 (1608 metric) surface-mount package. It provides an impedance of 10 Ohms at a test frequency of 100 MHz with a tolerance of 25%. The component supports a maximum DC current of 500 mA and has a maximum DC resistance of 250 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 electromagnetic interference suppression through high-impedance characteristics at target frequencies
• Automotive-grade reliability certified under the AEC-Q200 standard for durability
• Designed for surface-mount assembly using standard SMD/SMT termination styles

Chip Ferrite Bead Applications

• Noise filtering in automotive electronic circuits
• Signal line protection in compact mobile devices
• EMI suppression on data lines requiring low-profile components

Chip Ferrite Bead Procurement Notes

Verify the specific suffix against official Murata documentation, as variations may indicate differences in packaging or tape-and-reel specifications. Confirm that the 0603 footprint matches the design layout. Ensure the 500 mA current rating aligns with the circuit's operational requirements to prevent saturation or excessive heating during use.

Chip Ferrite Bead Selection Notes

Select this component when a low-impedance path is required for noise attenuation without significant signal loss. The 10 Ohm value suits applications needing mild filtering. Verify that the physical dimensions fit the available board space. Consider the thermal performance at the rated current to ensure stable operation across the specified temperature range.

Chip Ferrite Bead Part Context

This part belongs to the BLM18 series of multilayer ferrite beads manufactured by Murata Electronics. The series offers various impedance values in standardized footprints. The BLM18BA variant specifically targets automotive and industrial applications requiring robust EMI suppression in small form factors.

Chip Ferrite Bead Replacement Considerations

Check for direct substitutes within the BLM18 family with identical impedance and current ratings. Verify pin compatibility and mechanical dimensions before swapping. Consult Murata’s SimSurfing tool for electrical comparison if alternative brands are considered.
