BLM15BB050SN1D

Chip Ferrite Bead Overview

The Murata BLM15BB050SN1D is a single-line ferrite chip bead designed for surface mount applications. It features a 0402 (1005 metric) package with dimensions of 1.00mm length, 0.55mm width, and 0.55mm height. The component provides an impedance of 5 Ohms at a test frequency of 100 MHz. It supports a maximum DC current of 500mA and has a maximum DC resistance of 80 milliohms. The device operates within a temperature range of -55°C to +125°C and complies with RoHS3 standards.

Chip Ferrite Bead Feature Summary

• Provides signal line noise filtering through high-impedance characteristics at specific frequencies.
• Utilizes a compact monolithic ferrite construction suitable for space-constrained surface mount layouts.
• Maintains stable electrical performance across a wide industrial operating temperature range.

Chip Ferrite Bead Applications

• High-speed data line noise suppression in portable electronic devices
• Power supply input filtering for integrated circuits
• Clock signal attenuation in digital communication interfaces

Chip Ferrite Bead Procurement Notes

Verify the exact part number against manufacturer documentation to ensure correct impedance and current ratings. Confirm package compatibility with PCB footprint designs. Check for RoHS3 compliance requirements relevant to the target market. Validate supplier authenticity through authorized distribution channels to prevent counterfeit components.

Chip Ferrite Bead Selection Notes

Select this component when a low-impedance filter is required for signals carrying up to 500mA. The 0402 package size is appropriate for dense board layouts. Ensure the application frequency aligns with the 100 MHz test point for effective attenuation. Consider thermal management if continuous current approaches the maximum rating.

Chip Ferrite Bead Part Context

This component belongs to the Murata EMIFIL BLM15 series of ferrite beads. The series offers various impedance values and current ratings within standard SMD packages. The BLM15BB variant specifically denotes the 0402 form factor with standardized termination materials for reliable soldering.

Chip Ferrite Bead Replacement Considerations

Cross-reference with other BLM15BB050 variants from Murata or equivalent ferrite beads from TDK and Yageo. Verify that substitute parts match the 5 Ohm impedance at 100 MHz and the 500mA current handling capability. Ensure physical dimensions remain compatible with existing footprints.
