MFBW1V2012-050-R

Overview

The Eaton MFBW1V2012-050-R is a multilayer chip ferrite bead in an 0805 (2012 metric) surface-mount package. It provides 5 Ohms impedance at a test frequency of 100 MHz with a maximum DC current rating of 3.0 Amperes. The component features a maximum DC resistance of 30 mOhms and operates within a temperature range of -40°C to +85°C. Impedance tolerance ranges from 0 to 15 Ohms, and the unit weighs approximately 50 mg.

Feature Summary

• Multilayer construction for compact high-frequency noise suppression
• Shielded design to minimize electromagnetic interference
• High current handling capability suitable for power line filtering

Applications

• Power supply output filtering
• DC-DC converter noise attenuation
• High-speed digital signal line protection

Procurement Notes

Verify the specific suffix and impedance value against the target schematic requirements. Confirm that the 3.0 A current rating meets the circuit's peak load conditions. Ensure the 0805 footprint matches the PCB land pattern. Check RoHS compliance status if required by regulatory standards. Validate the operating temperature range against the environmental specifications of the final assembly.

Selection Notes

Select this component when a low-impedance path is required for high-current applications while attenuating high-frequency noise. The 5 Ohm impedance offers minimal insertion loss for DC signals compared to higher impedance beads. The 0805 package balances size constraints with thermal dissipation capabilities. Consider the 30 mOhm DCR impact on voltage drop during continuous operation.

Part Context

This part belongs to the MFBW1V series of multilayer chip ferrite beads manufactured by Eaton Electronics Division. The series utilizes proprietary ceramic materials to provide stable performance across varying temperatures. The 0805 form factor is widely used in consumer electronics and industrial equipment where space efficiency is critical.

Replacement Considerations

Cross-reference with other 0805 ferrite beads rated for 3.0 A and 5 Ohms impedance. Verify compatibility of terminal metallurgy and reflow soldering profiles. Ensure substitute components meet the same thermal and electrical safety standards.
