BLM15BB220SH1D

Chip Ferrite Bead Overview

The Murata BLM15BB220SH1D is a surface-mount chip ferrite bead in the BLM15_H series, housed in a 0402 (1005 metric) package. It provides an impedance of 22 ohms at 100 MHz with a tolerance of 25%. The component supports a maximum DC current of 300 mA and has a maximum DC resistance of 200 mOhms. It operates within a temperature range of -55°C to +125°C and meets AEC-Q200 qualification standards.

Chip Ferrite Bead Feature Summary

• Provides effective noise suppression for high-speed signal lines through ferrite material properties
• AEC-Q200 qualified for automotive reliability requirements
• Compact 0402 surface-mount design suitable for space-constrained PCB layouts

Chip Ferrite Bead Applications

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

Chip Ferrite Bead Procurement Notes

Verify the specific suffix SH1D against official Murata documentation to confirm terminal plating and packaging configuration. Ensure the selected variant matches the required impedance tolerance and current rating for the target circuit application before procurement.

Chip Ferrite Bead Selection Notes

Select this component when a 22-ohm impedance at 100 MHz is required for EMI suppression in compact designs. The 300 mA current rating must be sufficient for the signal line load. Verify that the 0402 footprint aligns with the PCB layout constraints and that AEC-Q200 compliance is necessary for the end-use environment.

Chip Ferrite Bead Part Context

This part belongs to the Murata BLM15 series of chip ferrite beads, designed for noise suppression in digital and analog circuits. The series offers various impedance values in standard packages, with the BB suffix indicating specific terminal configurations and the H suffix denoting the impedance characteristic curve.

Chip Ferrite Bead Replacement Considerations

Direct substitutes include other Murata BLM15BB220 variants with compatible suffixes such as SZ1D or SN1D, provided terminal and packaging specifications match the original requirement.
