MFBM1V2012-050-R

Overview

The MFBM1V2012-050-R is a multilayer chip ferrite bead from Eaton Electronics, designed for surface-mount technology in the 0805 (2012 metric) package. It provides an impedance of 0 to 15 Ohms at a test frequency of 100 MHz. The component supports a maximum DC current of 6 A with a maximum DC resistance of 10 mOhms. Operating temperatures range from -40°C to +85°C. Dimensions are 2.0 mm length, 1.25 mm width, and 1.0 mm height.

Feature Summary

• Multilayer construction for effective electromagnetic interference suppression
• Shielded design to minimize external magnetic field interaction
• High current handling capability suitable for power line applications

Applications

• Power supply filtering in electronic circuits
• Electromagnetic interference suppression on data lines
• Signal integrity protection in high-speed digital systems

Procurement Notes

Verify the specific impedance tolerance band required for the application, as the part number indicates a range of 0 to 15 Ohms rather than a fixed value. Confirm that the 6 A current rating aligns with peak operational loads. Ensure the 0805 footprint matches the PCB layout constraints. Check RoHS compliance status if restricted substances are a concern for the target market.

Selection Notes

Select this component when a compact surface-mount solution is needed for moderate current levels up to 6 A. The 0805 package offers a balance between current capacity and board space efficiency compared to smaller footprints. Consider the low DC resistance to minimize voltage drop in power distribution networks. Evaluate the impedance characteristics against the noise spectrum requiring attenuation.

Part Context

This component belongs to the MFBM1V series of multilayer ferrite beads manufactured by Eaton Electronics Division. The series utilizes proprietary materials to provide stable performance across temperature variations. These beads are engineered for EMI suppression in consumer electronics, industrial equipment, and automotive applications where space is limited.

Replacement Considerations

Cross-reference with other 0805 ferrite beads rated for 6 A and similar impedance ranges. Verify pin compatibility and thermal characteristics before substitution. Ensure the alternative component meets the same operating temperature and current specifications.
