MFBM1V1005-201-R

Overview

The MFBM1V1005-201-R is a multilayer ferrite chip bead designed for electromagnetic interference suppression in surface-mount applications. Manufactured by Eaton Electronics, this component operates within a temperature range of -40°C to +85°C and features a 0402 (1005 metric) package with dimensions of 1.00mm x 0.50mm x 0.65mm maximum height. It provides an impedance of 200 Ohms at 100 MHz with a tolerance of ±25%. The device supports a maximum DC current rating of 700mA and exhibits a maximum DC resistance of 250 mOhms. It is compliant with RoHS3 standards and has a moisture sensitivity level of 1.

Feature Summary

• Multilayer construction for effective EMI suppression in compact footprints
• High current handling capability suitable for power line filtering
• Shielded design to minimize external magnetic field interaction

Applications

• Power supply output filtering
• DC/DC converter noise attenuation
• General-purpose EMI suppression on signal lines

Procurement Notes

Verify the specific suffix 'R' indicates reel packaging configuration when ordering. Confirm that the 0402 package size aligns with PCB land pattern requirements. Ensure the 700mA current rating meets circuit load demands under operating temperature conditions. Check RoHS3 compliance status if required by project specifications. Validate supplier authenticity through authorized distribution channels.

Selection Notes

Select this component when high current capacity is required alongside moderate impedance values in a small form factor. Compare against MFBW1V series variants if lower current or different impedance characteristics are needed. Consider thermal derating curves for operation near the upper temperature limit. Evaluate DCR impact on voltage drop for sensitive power rails.

Part Context

This part belongs to the MFBM1V1005 series of multilayer ferrite beads from Eaton Electronics. The series offers various impedance and current ratings within the same 0402 footprint. It is distinct from the MFBW1V series which may have different core material properties or current handling capabilities despite similar physical dimensions.

Replacement Considerations

Direct substitutes include other MFBM1V1005 variants with matching impedance and current ratings such as MFBM1V1005-221-R. Cross-reference electrical parameters strictly before substitution. Physical compatibility is maintained across the 0402 family but functional equivalence must be verified.
