MFBM1V2012-070-R

Overview

The MFBM1V2012-070-R is a multilayer ferrite chip bead manufactured by Eaton Electronics Division, designed for EMI suppression in surface-mount applications. It features an 0805 (2012 metric) package with dimensions of 2.0 mm length, 1.25 mm width, and 1.0 mm height. The component provides an impedance of 7 Ohms at 100 MHz and supports a maximum DC current of 6 A. Its maximum DC resistance is 0.01 Ohms, ensuring minimal signal loss while effectively attenuating high-frequency noise.

Feature Summary

• Multilayer construction for effective electromagnetic interference suppression
• High current handling capability suitable for power line filtering
• Low DC resistance to minimize voltage drop and power loss

Applications

• Power supply output filtering
• DC-DC converter noise attenuation
• General-purpose EMI suppression on data lines

Procurement Notes

Verify the specific impedance tolerance and current rating against the official Eaton datasheet before integration. Confirm that the 0805 footprint matches the target PCB layout. Ensure compliance with RoHS3 standards if required by the end product specifications. Cross-reference the manufacturer part number to avoid confusion with similar series components.

Selection Notes

Select this component when a balance between high current capacity and moderate impedance is required in a compact 0805 package. The 6 A rating makes it suitable for powering sensitive circuits where noise immunity is critical. Consider thermal management capabilities during operation at maximum rated current.

Part Context

This part belongs to the MFBM1V series of multilayer ferrite beads from Eaton Electronics. The series offers various impedance values and current ratings across different package sizes, including 0402, 0603, 0805, and 1206. The MFBM1V2012 variant specifically targets applications requiring robust performance in space-constrained designs.

Replacement Considerations

Direct substitutes include other Eaton MFBM1V2012 variants with similar impedance, such as MFBM1V2012-090-R or MFBM1V2012-101-R, provided their current ratings meet the application requirements. Verify physical dimensions and electrical characteristics before substitution.
