BLM15AG221SH1D

Chip Ferrite Bead Overview

The Murata BLM15AG221SH1D is a chip ferrite bead in the BLM15_H series, housed in a 0402 (1005 metric) surface-mount package. It provides an impedance of 220 Ohms with a 25% tolerance at a test frequency of 100 MHz. The component supports a maximum DC current of 300 mA and has a maximum DC resistance of 350 mOhms. It operates within a temperature range of -55°C to +125°C and meets AEC-Q200 automotive qualification standards.

Chip Ferrite Bead Feature Summary

• Provides high-frequency noise suppression through significant impedance characteristics at 100 MHz.
• Designed for compact circuit layouts utilizing the standard 0402 surface-mount footprint.
• Qualified for automotive applications under the AEC-Q200 reliability standard.

Chip Ferrite Bead Applications

• EMI suppression filters
• Automotive electronic circuits
• General-purpose signal line filtering

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 AEC-Q200 qualification status for automotive integration. Cross-reference the impedance tolerance and DC current ratings with the target circuit design specifications before finalizing procurement orders.

Chip Ferrite Bead Selection Notes

Select this component when a 0402 footprint is required for space-constrained designs. The 300 mA current rating suits low-power signal lines rather than high-current power rails. Verify that the 220 Ohm impedance at 100 MHz aligns with the specific noise frequencies present in the application environment.

Chip Ferrite Bead Part Context

This part belongs to the Murata BLM15 series of chip ferrite beads. The AG designation typically indicates specific material properties optimized for high-frequency attenuation. The H series denotes the specific product line configuration within the manufacturer's ferrite bead portfolio.

Chip Ferrite Bead Replacement Considerations

Consult official Murata substitution guides for verified equivalents. Generic cross-references may not match the precise AEC-Q200 qualification or impedance curve requirements.
