MFBM1V1005-221-R

Overview

The MFBM1V1005-221-R is a multilayer ferrite chip bead designed for EMI suppression in surface-mount applications. It features a 0402 (1005 Metric) package with an impedance of 220 Ohms at 100 MHz and a tolerance of ±25%. The component supports a maximum current rating of 600 mA and exhibits a DC resistance of 300 mOhm. It operates within a temperature range of -40°C to +85°C and complies with RoHS standards.

Feature Summary

• Multilayer ferrite construction for effective electromagnetic interference suppression
• Compact 0402 surface-mount footprint suitable for space-constrained designs
• High current handling capability relative to package size

Applications

• Power line filtering in portable electronic devices
• Signal integrity protection in high-speed data lines
• EMI mitigation in consumer electronics power supplies

Procurement Notes

Verify the specific suffix and impedance value against the official Eaton datasheet to ensure compatibility with design requirements. Confirm that the 0402 package dimensions align with the PCB layout constraints. Check for RoHS compliance documentation if required by regulatory standards. Ensure the selected distributor provides genuine components from Eaton Electronics Division to avoid counterfeit risks.

Selection Notes

Select this component when a compact ferrite bead is needed for EMI suppression on low-current lines. The 220 Ohm impedance at 100 MHz targets common noise frequencies in digital circuits. The 600 mA rating suits applications where current draw remains below this threshold. Consider the 0402 size for dense board layouts. Verify thermal performance within the specified -40°C to +85°C operating range.
