BLA2ABB100SN4D

Chip Ferrite Bead Overview

The BLA2ABB100SN4D is a ferrite chip bead array manufactured by Murata Electronics, designed for electromagnetic interference suppression in surface-mount applications. It features a compact 0804 (2010 metric) package with dimensions of 2 mm length, 1 mm width, and 0.5 mm height. The component provides an impedance of 10 Ohms at a test frequency of 100 MHz with a tolerance of 25%. It supports a maximum DC current of 200 mA and has a maximum DC resistance of 100 mOhms. The device operates within a temperature range of -55°C to +125°C.

Chip Ferrite Bead Feature Summary

• Integrated four-line configuration for simultaneous noise filtering across multiple signal paths
• Compact surface-mount design suitable for high-density PCB layouts
• Low DC resistance characteristics to minimize signal loss in power or data lines

Chip Ferrite Bead Applications

• Noise suppression for digital signal lines in portable electronic devices
• EMI filtering in automotive infotainment and control systems
• Signal integrity protection in industrial communication interfaces

Chip Ferrite Bead Procurement Notes

Verify the specific suffix SN4D against official Murata documentation to confirm packaging and material specifications. Ensure compatibility with standard reflow soldering profiles for 0804 arrays. Cross-reference impedance values at 100 MHz with circuit simulation requirements. Confirm RoHS compliance status through the manufacturer's latest datasheet before final procurement approval.

Chip Ferrite Bead Selection Notes

Select this component when multi-line EMI suppression is required in a minimal footprint. The 10-ohm impedance offers moderate attenuation suitable for lower-frequency noise. Evaluate the 200 mA current rating against peak load conditions to prevent saturation. Compare physical dimensions against available board space constraints relative to single-line alternatives.

Chip Ferrite Bead Part Context

This part belongs to the Murata BLA series of ferrite chip bead arrays. These components are engineered for high-performance noise suppression in compact electronic assemblies. The BLA2ABB variant specifically denotes a four-line array structure within the broader EMIFIL product family, targeting complex signal routing scenarios.
