MFBM1V2012-090-R

Overview

The MFBM1V2012-090-R is a multilayer chip ferrite bead manufactured by Eaton Electronics. It features an impedance of 9 ohms at a test frequency of 100 MHz and supports a maximum DC current of 6 A. The component has a maximum DC resistance of 50 milliohms and operates within a temperature range of -40°C to +85°C. It utilizes a shielded design in an 0805 (2012 metric) surface-mount package with dimensions of 2.0 mm length, 1.25 mm width, and 1.2 mm height.

Feature Summary

• Multilayer chip construction for EMI suppression
• Shielded design to minimize magnetic interference
• High current handling capability for power line applications

Applications

• Power line filtering
• EMI suppression circuits
• Signal integrity protection

Procurement Notes

Verify the specific impedance tolerance and DC current ratings against the official Eaton datasheet before integration. Confirm that the 0805 footprint matches the target PCB layout. Ensure the operating temperature range meets the environmental requirements of the final assembly. Cross-reference the manufacturer part number to avoid confusion with similar series components.

Selection Notes

Select this component when high current capacity is required alongside effective high-frequency noise attenuation. The shielded structure makes it suitable for dense layouts where magnetic coupling must be minimized. Compare the 9-ohm impedance specification against the target noise spectrum to ensure adequate suppression. Verify that the low DC resistance minimizes voltage drop in the power path.

Part Context

This ferrite bead belongs to the MFBM1V series from Eaton Electronics, designed for multilayer chip applications. The series offers various impedance values and current ratings in standard SMD packages. This specific model provides a balance of high current handling and moderate impedance for general-purpose EMI control in electronic systems.

Replacement Considerations

Compatible substitutes include other 9-ohm, 0805-sized multilayer ferrite beads with equivalent current ratings. Verify physical dimensions and terminal configurations to ensure mechanical compatibility. Check that alternative parts meet the same impedance and DC resistance specifications.
