BLM21AG471SZ1D

Chip Ferrite Bead Overview

The Murata BLM21AG471SZ1D is a single-line ferrite bead chip in the EMIFIL BLM21 series, housed in an 0805 (2012 metric) surface-mount package. It provides an impedance of 470 Ohms at 100 MHz with a maximum DC resistance of 350 milliohms and a rated current of 600 mA. The component operates within a temperature range of -55°C to +125°C and meets AEC-Q200 automotive qualification standards.

Chip Ferrite Bead Feature Summary

• AEC-Q200 qualified for automotive reliability requirements
• High current handling capability up to 600 mA
• Compact 0805 footprint for space-constrained designs

Chip Ferrite Bead Applications

• Automotive electronic noise suppression
• Power line filtering in vehicle systems
• General-purpose signal line noise reduction

Chip Ferrite Bead Procurement Notes

Verify the specific suffix 'SZ1D' against official Murata documentation to confirm exact tolerance and packaging specifications. Ensure the selected variant aligns with required automotive qualification standards and thermal performance limits for the target application environment.

Chip Ferrite Bead Selection Notes

Select this component when high current capacity is required alongside moderate impedance in a standard 0805 package. Compare against lower-current alternatives if power dissipation exceeds limits. Confirm that the 470 Ohm impedance profile matches the target noise frequency spectrum effectively.

Chip Ferrite Bead Part Context

This part belongs to the Murata BLM21 series of ferrite beads, designed for suppressing electromagnetic interference in compact electronic circuits. The series offers various impedance and current ratings within standardized footprints to support diverse design constraints across consumer and industrial sectors.

Chip Ferrite Bead Replacement Considerations

BLM21BB471SZ1D: Higher current rating but different DCR. BLM21BD471SN1D: Lower current rating. Verify electrical parameters and package compatibility before substitution.
