BLM15BB221SH1D

Chip Ferrite Bead Overview

The Murata BLM15BB221SH1D is a single-line chip ferrite bead in the BLM15_H series, designed for surface-mount applications. It features an impedance of 220 Ohms at a test frequency of 100 MHz with a tolerance of 25%. The component supports a maximum DC current of 500 mA and has a maximum DC resistance of 80 mOhms. It operates within a temperature range of -55°C to +125°C. The physical dimensions are 1 mm in length, 0.5 mm in width, and 0.5 mm in height, corresponding to the 0402 (1005 metric) package. It holds AEC-Q200 qualification.

Chip Ferrite Bead Feature Summary

• Provides high-frequency noise suppression through significant impedance characteristics at 100 MHz.
• Features a compact 0402 surface-mount footprint suitable for space-constrained designs.
• Capable of handling up to 500 mA of direct current without saturation.

Chip Ferrite Bead Applications

• High-speed signal line filtering
• EMI suppression filters

Chip Ferrite Bead Procurement Notes

Verify the specific suffix 'H1D' against official Murata documentation to confirm packaging type and tape-and-reel specifications. Ensure the procurement channel sources genuine components from authorized distributors to guarantee compliance with RoHS standards and AEC-Q200 automotive reliability requirements. Cross-reference the manufacturer part number directly with the datasheet to avoid substitution errors.

Chip Ferrite Bead Selection Notes

Select this component when a 0402 footprint is required for EMI suppression with a 220 Ohm impedance target. The 500 mA current rating distinguishes it from lower-current variants like the SN1D series. Verify that the application environment stays within the specified -55°C to +125°C operating range. Confirm that the low DC resistance of 80 mOhms meets the voltage drop constraints of the power rail.

Chip Ferrite Bead Part Context

This component belongs to the Murata BLM15_H series of chip ferrite beads. It shares the same electrical impedance profile as other members of the series but differs in packaging and performance grades indicated by the suffix. The BLM15 series is engineered for general-purpose noise suppression in portable electronic devices and automotive electronics requiring small form factors.

Chip Ferrite Bead Replacement Considerations

BLM15BB221SN1D: Offers identical 220 Ohm impedance but rated for 200 mA max DC current and 800 mOhm DCR. Not a direct substitute for high-current applications.
