MFBA2V1005-900-R

Chip Ferrite Bead Overview

The MFBA2V1005-900-R is a multilayer chip ferrite bead manufactured by Eaton Electronics. It features a 0402 (1005 metric) surface-mount package with dimensions of 1 mm length, 0.5 mm width, and 0.5 mm height. The component provides an impedance of 90 Ohms at 100 MHz and supports a maximum DC current of 3.0 A. It has a maximum DC resistance of 40 mOhms and operates within a temperature range of -55°C to +150°C.

Chip Ferrite Bead Feature Summary

• Automotive-grade reliability for high-current applications
• Compact 0402 footprint for space-constrained designs
• High current handling capability up to 3.0 A

Chip Ferrite Bead Applications

• Automotive electronics signal line protection
• High-current power supply filtering
• Noise suppression in compact mobile devices

Chip Ferrite Bead Procurement Notes

Verify the specific suffix 'R' indicates reel packaging when ordering. Confirm the impedance value matches the design requirement of 90 Ohms at 100 MHz. Ensure the 3.0 A current rating aligns with the circuit's maximum load. Check RoHS compliance status if required by project specifications. Validate the operating temperature range suitability for the intended environment.

Chip Ferrite Bead Selection Notes

Select this component when a low-inductance, high-current ferrite bead is needed for EMI suppression. The 0402 size allows for dense PCB layouts. Consider the 40 mOhms DCR for minimal voltage drop in power lines. The automotive qualification ensures durability in harsh environments. Compare against other MFBA series variants for different impedance or current needs.

Chip Ferrite Bead Part Context

This part belongs to Eaton's MFBA2V1005 series of automotive multilayer chip ferrite beads. The series is designed for noise suppression in automotive and industrial applications. It utilizes proprietary materials to achieve high current ratings in a small form factor. The product line emphasizes reliability and performance under thermal stress.

Chip Ferrite Bead Replacement Considerations

Consult Eaton documentation for direct cross-references. Verify that any substitute maintains the 90 Ohm impedance and 3.0 A current rating. Ensure the replacement fits the 0402 package dimensions. Check for equivalent automotive qualification standards.
