BLA2ABB121SN4D

Chip Ferrite Bead Overview

The BLA2ABB121SN4D is a ferrite bead array manufactured by Murata Electronics, designed for signal line noise suppression. It features four independent channels within a compact 0804 (2010 metric) surface-mount package measuring 2.00mm x 1.00mm x 0.60mm. The component provides an impedance of 120 Ohms at a test frequency of 100 MHz with a tolerance of 25%. It supports a maximum DC current of 50mA and has a maximum DC resistance of 600 milliohms. The device operates reliably across a temperature range of -55°C to +125°C and complies with RoHS3 standards.

Chip Ferrite Bead Feature Summary

• Integrates four independent ferrite bead channels in a single compact footprint for multi-line signal filtering.
• Provides high impedance characteristics at 100 MHz to effectively attenuate high-frequency electromagnetic interference.
• Engineered for low DC resistance to minimize signal loss while maintaining robust noise suppression capabilities.

Chip Ferrite Bead Applications

Chip Ferrite Bead Procurement Notes

Verify the specific ordering suffix against official Murata documentation to ensure correct packaging and tape specifications. Confirm that the required impedance tolerance and current ratings align with the design constraints. Check for updated environmental compliance declarations such as RoHS3 status prior to final procurement authorization.

Chip Ferrite Bead Selection Notes

Select this component when space-constrained designs require multi-channel filtering in an 0804 package. Ensure the application current does not exceed the 50mA rating to prevent performance degradation. Consider the 600 milliohm DC resistance impact on signal integrity for sensitive low-voltage lines.
