BLM21BB050SN1D

Chip Ferrite Bead Overview

The Murata BLM21BB050SN1D is a single-line ferrite bead designed for high-speed signal line noise suppression. It features an impedance of 5 Ohms at 100 MHz and supports a maximum DC current of 1A. The component has a maximum DC resistance of 20 milliohms and operates within a temperature range of -55°C to +125°C. It utilizes a 0805 (2012 metric) surface-mount package with dimensions of 2.00mm x 1.25mm x 1.45mm.

Chip Ferrite Bead Feature Summary

• Suppresses high-frequency noise in high-speed signal lines
• Single-line configuration for efficient circuit integration
• Low DC resistance minimizes power loss

Chip Ferrite Bead Applications

• High-speed signal line noise filtering
• EMI suppression in electronic circuits

Chip Ferrite Bead Procurement Notes

Verify the complete part number including suffix SN1D to ensure correct packaging and specifications. Confirm RoHS3 compliance status as required by project regulations. Check moisture sensitivity level (MSL 1) requirements for storage and handling procedures before assembly.

Chip Ferrite Bead Selection Notes

Select this component when low impedance (5 Ohms) is required for high-current (1A) signal paths. The 0805 package offers a balance between current handling and board space. Ensure the application frequency aligns with the 100 MHz test frequency for accurate attenuation performance.

Chip Ferrite Bead Part Context

This component belongs to the Murata EMIFIL BLM21BB series, which specializes in chip ferrite beads for suppressing high-frequency noise. The series is engineered for use in compact electronic devices requiring effective EMI control without significant signal degradation.

Chip Ferrite Bead Replacement Considerations

Consult official Murata documentation for verified substitutes. Cross-referencing requires matching impedance, current rating, and package dimensions.
