MFBM1V1005-501-R

Overview

The Eaton MFBM1V1005-501-R is a multilayer chip ferrite bead designed for EMI suppression in surface-mount applications. It features a 0402 (1005 metric) package with dimensions of 1.0 mm length, 0.5 mm width, and 0.65 mm height. The component provides an impedance of 500 Ohms at a test frequency of 100 MHz with a tolerance of ±25%. It supports a maximum DC current of 500 mA and has a maximum DC resistance of 400 mOhms. The device operates within a temperature range of -40°C to +85°C and is RoHS compliant.

Feature Summary

• Multilayer construction for effective electromagnetic interference suppression
• Shielded design to contain magnetic fields
• Single-channel configuration for power line filtering

Applications

• Power supply input filtering
• High-speed data line noise suppression
• General-purpose EMI suppression in compact electronics

Procurement Notes

Verify the specific suffix 'R' indicates reel packaging when ordering. Confirm the impedance value of 500 Ohms matches the target noise frequency spectrum. Ensure the 500 mA current rating exceeds the peak operating current of the circuit to prevent saturation. Check RoHS compliance requirements against local regulations.

Selection Notes

Select this component when space constraints require a 0402 footprint. Choose based on the required 500 Ohm impedance at 100 MHz for the specific noise profile. Ensure the 500 mA current handling capability aligns with the application's power demands. Consider the -40°C to +85°C operating range for environmental suitability.

Part Context

This part belongs to the Eaton MFBM1V series of multilayer ferrite beads. The series is engineered for high-current applications in small form factors. The MFBM1V1005 designation specifies the 0402 case size and general family characteristics. This specific model offers a standardized impedance value for common EMI filtering needs.

Replacement Considerations

Direct substitutes include other 0402 ferrite beads with 500 Ohms impedance at 100 MHz and similar current ratings. Verify pin compatibility and physical dimensions before substitution. Cross-reference datasheets for impedance curves to ensure equivalent performance at target frequencies.
