BLM15BB050SZ1D

Chip Ferrite Bead Overview

The BLM15BB050SZ1D is a single-line ferrite bead from Murata Electronics, designed for noise suppression in electronic circuits. It features an impedance of 5 Ohms at a test frequency of 100 MHz and supports a maximum DC current of 500 mA. The component has a maximum DC resistance of 80 milliohms and operates within a temperature range of -55°C to +125°C. It utilizes a 0402 (1005 metric) surface-mount package with dimensions of 1.00 mm in length and 0.50 mm in width.

Chip Ferrite Bead Feature Summary

• Designed to function as a resistor at noise frequencies to reduce resonance possibilities
• Maintains signal waveform integrity during high-frequency noise attenuation
• Suitable for automotive infotainment applications requiring compact filtering

Chip Ferrite Bead Applications

• Automotive infotainment systems
• High-speed signal line noise suppression
• Compact consumer electronics circuitry

Chip Ferrite Bead Procurement Notes

Verify the specific suffix 'SZ1D' against official Murata documentation to confirm exact packaging and tape-and-reel specifications. Ensure compatibility with existing PCB footprints for the 0402 package size. Confirm RoHS3 compliance status through the manufacturer's latest datasheet before finalizing procurement orders.

Chip Ferrite Bead Selection Notes

Select this component when space constraints require a 0402 footprint for EMI suppression. The 5 Ohm impedance rating is appropriate for low-impedance lines where minimal signal loss is critical. Verify that the 500 mA current rating meets the operational requirements of the target circuit without causing excessive thermal rise or resistance increase.

Chip Ferrite Bead Part Context

This part belongs to the Murata EMIFIL BLM15 series, which focuses on small-form-factor noise filters. The series is engineered to provide effective electromagnetic interference suppression while preserving signal quality in dense printed circuit board layouts commonly found in modern automotive and portable devices.

Chip Ferrite Bead Replacement Considerations

BLM15BB050SN1D is a documented alternative within the same series offering identical electrical characteristics but potentially different packaging configurations.
