MFBM1V1005-101-R

Overview

The MFBM1V1005-101-R is a multilayer ferrite chip bead designed for EMI suppression in surface-mount applications. It features an impedance of 100 Ohms at 100 MHz and supports a maximum DC current of 800 mA. The component has a maximum DC resistance of 150 mOhms and operates within a temperature range of -40°C to +85°C. Housed in a compact 0402 (1005 metric) package, it provides effective noise filtering for power lines while maintaining low insertion loss.

Feature Summary

• Multilayer construction for high-density circuit board integration
• Effective electromagnetic interference suppression on single power lines
• Compact footprint suitable for space-constrained designs

Applications

• Power line filtering in portable electronic devices
• Noise suppression in mobile communication equipment
• EMI mitigation in consumer electronics power circuits

Procurement Notes

Verify the specific impedance tolerance and current rating against the latest official Eaton datasheet before finalizing design specifications. Confirm that the 0402 package dimensions align with your PCB land pattern requirements. Ensure compatibility with standard reflow soldering profiles for multilayer ceramic components to maintain reliability during assembly processes.

Selection Notes

Select this component when a low-profile ferrite bead is required for single-line power filtering. The 800 mA current rating makes it suitable for moderate power applications where space is limited. Compare its impedance characteristics against alternative series like MFBW1V or MCL if higher current handling or different impedance values are needed for the specific circuit topology.

Part Context

This part belongs to the MFBM1V1005 series from Eaton Electronics Division, which specializes in multilayer ferrite chips for EMI suppression. The series offers various impedance options within the 0402 package size, allowing designers to tailor noise filtering performance without increasing the component footprint on the printed circuit board.

Replacement Considerations

Direct substitutes include other Eaton MFBM1V1005 variants with similar impedance ratings, such as the MFBM1V1005-121-R. Cross-brand replacements require matching the 100 Ohm impedance at 100 MHz, 800 mA current rating, and 0402 package dimensions to ensure mechanical and electrical compatibility.
