BLA2ABD750SN4D

Chip Ferrite Bead Overview

The BLA2ABD750SN4D is a ferrite chip bead array manufactured by Murata Electronics. It features four independent circuits housed in an 0804 (2012 metric) surface-mount package with dimensions of 2.0 mm length, 1.25 mm width, and 0.5 mm height. The component provides an impedance of 75 Ohms at a test frequency of 100 MHz and supports a maximum DC current of 200 mA. It operates within a temperature range of -55°C to +125°C and has a maximum DC resistance of 200 mOhms.

Chip Ferrite Bead Feature Summary

• Integrates four independent ferrite bead circuits into a single compact package for space-efficient designs.
• Provides high-speed signal filtering capabilities suitable for sensitive data lines.
• Utilizes a robust surface-mount construction compatible with standard SMD/SMT assembly processes.

Chip Ferrite Bead Applications

• High-performance wireless communication systems
• Data line protection in portable electronic devices
• Signal integrity management in high-speed digital interfaces

Chip Ferrite Bead Procurement Notes

Verify the specific ordering suffix against the official Murata datasheet to ensure correct packaging and tolerance specifications. Confirm that the 0804 footprint matches the target PCB layout requirements. Ensure the selected variant meets the required RoHS compliance standards for the intended market. Cross-reference the maximum DC current rating with the circuit's operational load to prevent saturation.

Chip Ferrite Bead Selection Notes

Select this component when multiple signal lines require noise suppression in a constrained board area. The four-circuit configuration reduces component count compared to discrete beads. Ensure the 75 Ohm impedance aligns with the target noise frequencies. Verify that the 200 mA current rating exceeds the peak operating current of the protected lines to maintain performance stability.
