MFBA2V2012P-111-R

Overview

The MFBA2V2012P-111-R is a surface-mount ferrite bead from Eaton Electronics, designed for high-current noise suppression in compact electronic assemblies. Housed in an 0805 (2012 metric) package with dimensions of 2.00mm x 1.25mm and a maximum height of 1.05mm, this component provides 110 Ohms impedance at 100 MHz. It supports a maximum DC current rating of 5A with a maximum DC resistance of 13mOhms. The device operates within a temperature range of -55°C to 150°C and meets AEC-Q200 automotive reliability standards.

Feature Summary

• High current handling capability suitable for power line filtering applications
• Automotive-grade reliability certified under AEC-Q200 standards
• Compact molded surface-mount construction for space-constrained PCB layouts

Applications

• Automotive electronics noise suppression
• High-current DC power line filtering
• Signal integrity protection in compact consumer devices

Procurement Notes

Verify the specific impedance value and current ratings against the official Eaton datasheet before integration. Confirm that the 0805 footprint matches the target PCB design. Ensure the operating temperature range aligns with the final application environment. Check for RoHS compliance status as indicated in the manufacturer documentation.

Selection Notes

Select this component when high current capacity is required alongside effective high-frequency noise attenuation. The low DC resistance minimizes voltage drop in power paths. The AEC-Q200 certification makes it suitable for automotive environments where thermal stability and durability are critical requirements.

Part Context

This ferrite bead belongs to Eaton's MFB series of chip beads, which are engineered for EMI suppression in modern electronic circuits. The V2 suffix typically denotes a specific generation or material composition optimized for higher current handling compared to standard variants. It serves as a passive component to dampen high-frequency interference without significantly affecting the DC signal path.

Replacement Considerations

Consult Eaton's official cross-reference tools for verified substitutes. Ensure any replacement maintains the 110 Ohm impedance at 100 MHz and supports at least 5A current. Verify that alternative components meet the same AEC-Q200 automotive qualification if used in regulated industries.
