MFBM1V1005-050-R

Overview

The MFBM1V1005-050-R is a multilayer ferrite chip bead from Eaton Electronics, designed for EMI suppression in power lines. It features a 0402 (1005 metric) surface-mount package with dimensions of 1.00mm x 0.50mm x 0.65mm. The component provides an impedance of 5 Ohms at 100 MHz and supports a maximum DC current rating of 1.8A. Its maximum DC resistance (DCR) is 50 mOhms. It operates within a temperature range of -40°C to +85°C and complies with RoHS3 standards.

Feature Summary

• Multilayer construction for effective high-frequency noise attenuation
• Compact 0402 footprint suitable for space-constrained PCB layouts
• High current handling capability for power line applications

Applications

• Power supply output filtering
• DC-DC converter noise suppression
• General EMI suppression on data and power lines

Procurement Notes

Verify the specific impedance code suffix matches the required circuit specifications. Confirm the package size corresponds to the design footprint. Ensure the manufacturer part number aligns with the intended bill of materials. Check for RoHS3 compliance requirements if applicable to the final product regulations.

Selection Notes

Select this component when low impedance at DC is critical alongside moderate noise suppression. The 1.8A rating allows use in higher current power rails compared to higher impedance variants. Consider the 50 mOhm DCR impact on voltage drop. The 0402 size requires appropriate pick-and-place capabilities.

Part Context

This part belongs to the MFBM1V1005 series of multilayer ferrite beads. The series offers various impedance values tailored for different frequency and current requirements. All variants share the same 0402 physical dimensions and general thermal characteristics, differing primarily in their magnetic material properties and resulting impedance curves.

Replacement Considerations

Direct substitutes include other 0402 ferrite beads with similar 5 Ohm @ 100 MHz impedance and >1.8A current ratings. Verify pin compatibility and thermal performance before substitution.
