MFBA2V1005P-301-R

Chip Ferrite Bead Overview

The MFBA2V1005P-301-R is a single-line multilayer ferrite bead from the MFB series, manufactured by Eaton Electronics. It features a 0402 (1005 metric) surface-mount package with dimensions of 1.00mm x 0.50mm and a maximum height of 0.65mm. The component provides an impedance of 300 Ohms at 100 MHz and supports a rated current of 150 mA. Its maximum DC resistance is 1.2 Ohms. It operates within a temperature range of -40°C to +85°C and complies with RoHS3 standards.

Chip Ferrite Bead Feature Summary

• Multilayer chip construction for effective electromagnetic interference suppression
• Automotive-grade reliability certified under AEC-Q200 standards
• Compact 0402 footprint designed for high-density surface-mount applications

Chip Ferrite Bead Applications

• EMI suppression in automotive electronic circuits
• Signal line filtering in compact mobile devices
• Power rail noise reduction in consumer electronics

Chip Ferrite Bead Procurement Notes

Verify the specific suffix 'P' indicates automotive qualification status against the official Eaton datasheet. Confirm that the 150 mA rating aligns with your circuit's peak current requirements. Ensure the 0402 package size fits your PCB land pattern constraints. Check for RoHS3 compliance documentation if required by your manufacturing standards.

Chip Ferrite Bead Selection Notes

Select this component when space is limited to a 0402 footprint but higher current handling than standard beads is needed. Compare the 300 Ohm impedance profile against target noise frequencies to ensure adequate attenuation. Consider the 1.2 Ohm DC resistance impact on voltage drop in low-voltage power lines relative to alternative ferrite solutions.

Chip Ferrite Bead Part Context

This part belongs to the MFBW/MFBA series of multilayer ferrite beads designed for EMI suppression. It shares the 0402 form factor with other variants like the MFBM1V1005 series but offers distinct electrical characteristics tailored for specific current and impedance needs within the Eaton Electronics passive components portfolio.

Chip Ferrite Bead Replacement Considerations

Direct substitutes include the MFBW1V1005-301-R or MFBM1V1005-301-R, though current ratings and DC resistance values differ. Verify package compatibility and impedance curves before swapping to ensure equivalent noise suppression performance.
