BLA2ABB220SN4D

Chip Ferrite Bead Overview

The BLA2ABB220SN4D is a ferrite bead array manufactured by Murata Electronics, designed for signal line noise suppression. It features an impedance of 22 Ohms at 100 MHz and supports four independent signal lines within a single package. The component operates with a maximum DC current rating of 200 mA and exhibits a maximum DC resistance (DCR) of 200 milliohms. It utilizes a surface-mount 0804 (2010 metric) footprint with an eight-pad configuration. The device functions reliably across a temperature range of -55°C to +125°C.

Chip Ferrite Bead Feature Summary

• Integrates four independent ferrite bead channels in a compact surface-mount package for multi-line signal filtering.
• Provides low-impedance signal paths with minimal DC resistance to preserve signal integrity while attenuating high-frequency noise.

Chip Ferrite Bead Applications

• Noise suppression on parallel data buses
• Signal conditioning for high-speed digital interfaces
• EMI reduction in portable electronic devices

Chip Ferrite Bead Procurement Notes

Verify the specific suffix SN4D against the manufacturer's official datasheet to confirm pinout compatibility and impedance tolerance. Ensure the selected packaging format aligns with automated assembly requirements. Cross-reference the part number with authorized distributors to validate authenticity and traceability before procurement.

Chip Ferrite Bead Selection Notes

Select this component when space-constrained designs require filtering multiple signal lines simultaneously. The 0804 footprint offers a balance between current handling capacity and board area efficiency. Consider the 200 mA rating to ensure adequate margin for peak signal currents without saturation.

Chip Ferrite Bead Part Context

This part belongs to the Murata EMIFIL BLA2 series of chip ferrite bead arrays. These components are engineered for compact noise suppression applications where multiple signals require filtering within a limited PCB area. The series provides standardized impedance characteristics for common digital interface protocols.

Chip Ferrite Bead Replacement Considerations

BLA2ABB221SN4D: Offers higher impedance (220 Ohms) but lower current rating (50 mA). Verify if the increased attenuation and reduced current capacity meet the circuit requirements.
