MFBA3V2012K-300-R

Overview

The MFBA3V2012K-300-R is a single-line surface-mount ferrite bead from Eaton Electronics, designed for power line filtering applications. It exhibits an impedance of 30 Ohms at 100 MHz and supports a maximum current rating of 600 mA. The component features a maximum DC resistance (DCR) of 100 mOhm and operates within a temperature range of -40°C to +85°C. Packaged in a 0805 (2012 metric) footprint with dimensions of 2.00mm x 1.25mm, it meets AEC-Q200 automotive qualification standards.

Feature Summary

• AEC-Q200 qualified for automotive reliability requirements
• Single-line configuration for compact power circuit integration
• Low DC resistance to minimize power loss in high-current paths

Applications

• Automotive electronic power distribution networks
• High-frequency noise suppression on vehicle data buses
• EMI filtering in automotive infotainment systems

Procurement Notes

Verify the specific suffix 'K' against the manufacturer's latest datasheet to confirm package tolerance and termination material specifications. Ensure the selected variant aligns with the required AEC-Q200 certification level for your target application environment. Cross-reference the impedance value at 100 MHz with your circuit's noise profile to validate performance adequacy before finalizing procurement.

Selection Notes

Select this component when space constraints require an 0805 footprint with moderate current handling capabilities up to 600 mA. It is suitable for designs needing verified automotive-grade reliability without requiring higher current ratings found in larger packages. Consider the 30 Ohm impedance characteristic for targeting specific high-frequency interference bands common in automotive electronics.

Part Context

This part belongs to Eaton's MFBA3V2012 series of automotive chip beads. The series offers various impedance values while maintaining consistent physical dimensions and current ratings. It is engineered specifically for the stringent environmental and reliability demands of modern automotive electronic systems, providing a standardized solution for EMI suppression.

Replacement Considerations

Direct substitutes include other MFBA3V2012 variants with different impedance values if the electrical characteristics permit. Verify that any replacement maintains the same 0805 footprint, 600 mA current rating, and AEC-Q200 qualification status to ensure compatibility with existing board layouts and automotive compliance requirements.
