MFBW1V2012-000-R

Overview

The MFBW1V2012-000-R is a multilayer ferrite chip bead manufactured by Eaton Electronics Division, designed for electromagnetic interference (EMI) suppression in surface-mount applications. This component belongs to the MFBW1V series and features a 0805 (2012 metric) package with dimensions of 2.0 mm length, 1.25 mm width, and 1.0 mm maximum height. It exhibits an impedance of 0 Ohms at 100 MHz and supports a maximum DC current rating of 3.0 A. The device has a maximum DC resistance of 30 mOhms and operates within a temperature range of -40°C to +85°C.

Feature Summary

• Multilayer construction provides effective EMI noise attenuation in compact surface-mount form factors
• Zero-ohm impedance characteristic allows use as a bridge or filter element without signal loss at low frequencies
• High current handling capability of 3.0 A suitable for power line filtering applications

Applications

• Power supply input/output filtering
• Digital circuit noise suppression
• Signal line EMI mitigation

Procurement Notes

Verify the specific manufacturer part number against official Eaton documentation to ensure authenticity. Confirm that the received components match the specified 0805 package dimensions and electrical characteristics. Check for RoHS compliance markings if required by your assembly process. Ensure storage conditions maintain moisture sensitivity level 1 integrity prior to soldering.

Selection Notes

Select this component when a zero-ohm path with high current capacity is required for board layout flexibility or basic EMI filtering. The 3.0 A rating distinguishes it from lower-current variants in the same series. Consider the 0805 footprint availability on your PCB silkscreen and copper pad design. Verify that the 30 mOhm DCR meets your voltage drop constraints under maximum load conditions.

Part Context

This ferrite bead is part of Eaton's MFBW1V series of multilayer chip beads, which offers various impedance values and current ratings across different package sizes including 0402, 0603, 0805, and 1206. The series is engineered for general-purpose EMI suppression in consumer electronics, industrial equipment, and telecommunications devices where space-constrained filtering solutions are necessary.

Replacement Considerations

Cross-reference with other Eaton MFBW1V2012-XXX-R variants for different impedance needs. Verify equivalent parts from other manufacturers only if they match the 0805 footprint, 3.0 A current rating, and 30 mOhm DCR specifications exactly.
