BLM18EG471SZ1D

Chip Ferrite Bead Overview

The Murata BLM18EG471SZ1D is a single-line chip ferrite bead in the EMIFIL BLM18 series, housed in a 0603 (1608 metric) surface-mount package. It provides an impedance of 470 Ohms at a test frequency of 100 MHz with a tolerance of ±25%. The component supports a maximum DC current of 500 mA and exhibits a maximum DC resistance of 210 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

• Features a modified internal electrode structure designed to minimize stray capacitance for high-frequency signal integrity.

Chip Ferrite Bead Applications

• Automotive electronic circuits requiring AEC-Q200 qualified components
• High-speed signal line noise suppression
• Power supply filtering in compact surface-mount designs

Chip Ferrite Bead Procurement Notes

Verify the specific suffix against official Murata documentation to confirm physical dimensions and electrical characteristics. Confirm RoHS compliance status and moisture sensitivity level requirements prior to integration into the manufacturing process.

Chip Ferrite Bead Selection Notes

Select this component when low stray capacitance is critical for maintaining signal integrity in high-speed applications. Ensure the 500 mA current rating aligns with the circuit's operational load to prevent saturation or excessive heating during continuous use.

Chip Ferrite Bead Part Context

This part belongs to the BLM18E series, which utilizes specialized internal structures to reduce parasitic effects compared to standard ferrite beads. It serves as a passive filter element within the broader EMIFIL product family for EMI suppression.

Chip Ferrite Bead Replacement Considerations

Consult official substitution guides for equivalent parts within the BLM18 series. Verify that alternative components match the 0603 footprint, 470 Ohm impedance, and 500 mA current handling capabilities.
