MFBM1V1005-300-R

Overview

The MFBM1V1005-300-R is a multilayer chip ferrite bead manufactured by Eaton Electronics. It features a 0402 (1005 metric) surface-mount package with dimensions of 1 mm length, 0.5 mm width, and 0.5 mm height. The component provides an impedance of 30 Ohms at a test frequency of 100 MHz. It supports a maximum DC current of 1.3 A and has a maximum DC resistance of 80 mOhms. The impedance tolerance is ±25%. The device operates within a temperature range of -40°C to +85°C.

Feature Summary

• Multilayer construction for compact surface-mount integration
• High current handling capability suitable for power line filtering
• Shielded design to minimize electromagnetic interference

Applications

• Power line noise suppression in portable electronics
• EMI filtering in mobile communication devices
• Signal integrity protection in consumer hardware

Procurement Notes

Verify the specific suffix against official Eaton documentation to confirm electrical characteristics. Ensure the ordering part number matches the required impedance and current ratings. Confirm RoHS compliance status through the manufacturer's latest release notes. Validate that the package type aligns with the target PCB footprint requirements before finalizing procurement.

Selection Notes

Select this component when a low-profile 0402 ferrite bead is required for high-current applications. The 1.3 A rating distinguishes it from lower-current variants in the same series. Consider the 30 Ohm impedance value for targeted noise attenuation at 100 MHz. Evaluate the 80 mOhms DC resistance to ensure minimal voltage drop in the power path.

Part Context

This part belongs to the MFBM1V series of multilayer chip beads from Eaton Electronics. The series offers various impedance options within the standard 0402 footprint. These components are designed for general-purpose EMI suppression in space-constrained electronic assemblies.

Replacement Considerations

Cross-reference with other Eaton MFBM1V1005 variants such as MFBM1V1005-600-R for different impedance needs. Verify compatibility with alternative manufacturers offering equivalent 0402 ferrite beads with similar current and impedance specifications.
