BLA2ABD221SN4D

Chip Ferrite Bead Overview

The Murata BLA2ABD221SN4D is a ferrite bead array designed for signal line noise suppression. It features four independent channels within an 0804 (2010 metric) surface-mount package with an 8-pad footprint. The component provides an impedance of 220 Ohms at 100 MHz and supports a maximum DC current of 100mA per channel. Its maximum DC resistance is 400 milliohms, ensuring minimal signal loss in high-speed data paths.

Chip Ferrite Bead Feature Summary

• Four-channel configuration for simultaneous multi-line filtering
• Compact 0804 footprint optimized for dense PCB layouts
• Low DC resistance to preserve signal integrity

Chip Ferrite Bead Applications

• High-speed digital signal line noise suppression
• Data bus protection in compact electronic modules
• EMI reduction in portable devices

Chip Ferrite Bead Procurement Notes

Verify the specific suffix SN4D against the manufacturer's official datasheet to confirm pinout and electrical characteristics. Ensure the selected variant matches the required 100mA current rating and 220 Ohm impedance specifications for the target application circuit design.

Chip Ferrite Bead Selection Notes

Select this component when space constraints require a 0804 package size but multiple filtered lines are needed. Compare the 100mA current rating against the maximum expected signal current to prevent saturation. Evaluate the 400 milliohm DCR impact on voltage drop relative to the system power budget.

Chip Ferrite Bead Part Context

This part belongs to the Murata EMIFIL BLA2 series of ferrite chip bead arrays. These components are engineered for EMI suppression in high-density electronics. The BLA2 series offers various channel counts and impedances within standard industrial temperature ranges.

Chip Ferrite Bead Replacement Considerations

BLA2ABB221SN4D is a parameter-equivalent alternative from Murata. Verify that the substitute maintains identical impedance, current ratings, and physical dimensions before integration.
