MFBW1V2012-501-R

Overview

The Eaton MFBW1V2012-501-R is a multilayer chip ferrite bead designed for EMI suppression in surface-mount applications. It features a 0805 (2012 metric) package with dimensions of 2.0 mm length, 1.25 mm width, and 1.0 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 1.5 A and has a maximum DC resistance of 250 mOhms. The operating temperature range extends from -40°C to +85°C.

Feature Summary

• Multilayer construction for effective electromagnetic interference suppression
• Shielded design to minimize external magnetic field interaction
• Surface-mount termination for automated PCB assembly

Applications

• Power line filtering in portable electronic devices
• Signal integrity protection in high-speed data interfaces
• EMI suppression in automotive electronics modules

Procurement Notes

Verify the specific suffix and packaging configuration against the manufacturer's latest datasheet before ordering. Confirm that the 0805 footprint matches the target PCB layout. Ensure compliance with RoHS directives if required by the end product specifications. Cross-reference the part number with authorized distributors to confirm availability and authenticity.

Selection Notes

Select this component when a 500 Ohm impedance at 100 MHz is required for noise attenuation on power or signal lines. The 1.5 A current rating suits moderate power applications where low DC resistance is critical. Consider the 0805 package size for space-constrained designs requiring higher current handling than smaller footprints allow.

Part Context

This part belongs to the Eaton MFBW1V series of multilayer ferrite beads. The series offers various impedance values and current ratings within standard SMT packages. These components are engineered for general-purpose EMI suppression in consumer, industrial, and automotive electronics.

Replacement Considerations

Direct substitutes include other 500 Ohm, 1.5A ferrite beads in the 0805 package from manufacturers like Murata or TDK. Verify impedance curves and current ratings match exactly. Check pin compatibility and thermal characteristics before substitution.
