MFBW1V1005-260-R

Overview

The Eaton MFBW1V1005-260-R is a multilayer chip ferrite bead in a 0402 (1005 metric) surface-mount package. It provides an impedance of 26 Ohms at a test frequency of 100 MHz with a tolerance of ±25%. The component supports a maximum DC current of 700 mA and has a maximum DC resistance of 60 mOhms. It operates within a temperature range of -40°C to +85°C. Physical dimensions are 1 mm in length, 0.5 mm in width, and 0.5 mm in height.

Feature Summary

• Multilayer construction for compact SMT integration
• Shielded design to minimize electromagnetic interference
• High current handling capability for power line filtering

Applications

• Noise suppression on high-speed digital signal lines
• Power supply input/output filtering in portable devices
• EMI reduction in consumer electronics circuits

Procurement Notes

Verify the specific suffix '260' confirms the 26 Ohm impedance value, as the MFBW1V1005 series includes variants with different impedance ratings such as 0 Ohms or 100 Ohms. Confirm RoHS compliance status through official manufacturer documentation prior to final procurement decisions.

Selection Notes

Select this component when a 26 Ohm impedance at 100 MHz is required for noise attenuation in space-constrained designs. Ensure the circuit's DC current does not exceed 700 mA to prevent saturation. The 0402 footprint allows for dense PCB layouts compared to larger ferrite packages.

Part Context

This part belongs to the Eaton MFBW1V1005 series of multilayer chip beads. These components are designed for general-purpose EMI suppression in small form factor applications. The series offers various impedance values while maintaining consistent physical dimensions and thermal characteristics across the product line.

Replacement Considerations

Direct substitutes include other Eaton MFBW1V1005 series parts with identical 26 Ohm impedance, such as MFBW1V1005-260. Verify that alternative manufacturers offer matching 0402 footprints, 700 mA current ratings, and 26 Ohm impedance at 100 MHz.
