BLM15BD471SN1D

Chip Ferrite Bead Overview

The Murata BLM15BD471SN1D is a surface-mount ferrite chip bead from the EMIFIL BLM15 series, housed in a 0402 (1005 metric) package. It provides an impedance of 470 Ohms at 100 MHz with a tolerance of 25%. The component supports a maximum DC current of 200 mA and has a maximum DC resistance of 600 mΩ. It operates within a temperature range of -55°C to +125°C and features a single signal line configuration.

Chip Ferrite Bead Feature Summary

• Monolithic ferrite construction for effective high-frequency noise suppression
• Designed specifically for EMI filtering on high-speed signal lines
• Compact 0402 footprint suitable for space-constrained surface mount applications

Chip Ferrite Bead Applications

• High-speed signal line noise filtering
• EMI suppression filters
• Audio line noise reduction

Chip Ferrite Bead Procurement Notes

Verify the specific suffix SN1D against official Murata documentation to confirm packaging details and material compliance. Ensure the selected variant matches the required impedance tolerance and current rating for the target circuit design before finalizing procurement orders.

Chip Ferrite Bead Selection Notes

Select this component when a compact 0402 ferrite bead is required for 470 Ohm impedance at 100 MHz. Consider the 200 mA current limit and 600 mΩ DCR constraints. Verify compatibility with RoHS3 standards and REACH regulations for the intended market deployment.

Chip Ferrite Bead Part Context

This part belongs to the Murata EMIFIL BLM15 series, which offers various impedance values and current ratings in the 0402 package. It serves as a passive filter component for suppressing electromagnetic interference in electronic circuits, distinct from higher-current or larger-package variants like the BLM18 or BLM21 series.

Chip Ferrite Bead Replacement Considerations

Direct substitutes include other Murata parts with identical 470 Ohm impedance and 0402 dimensions, such as BLM15BX471SN1D or BLM15GG471SN1D, provided their current ratings and DC resistance values meet the specific application requirements.
