MFBW1V1005-700-R

Overview

The MFBW1V1005-700-R is a multilayer ferrite chip bead from Eaton Electronics, designed for surface-mount technology. It features a 0402 (1005 metric) package with dimensions of 1.00mm length and 0.50mm width. The component provides an impedance of 70 Ohms at a test frequency of 100 MHz. It supports a maximum DC current rating of 450mA and has a maximum DC resistance of 200 mOhms. The device operates within a temperature range of -40°C to +85°C.

Feature Summary

• Multilayer construction for effective electromagnetic interference suppression
• Shielded design to minimize external magnetic field interaction
• Compact 0402 footprint suitable for high-density circuit board layouts

Applications

• High-speed data line filtering in portable electronics
• Power supply noise attenuation in compact devices
• Signal integrity enhancement in dense PCB assemblies

Procurement Notes

Verify the specific impedance tolerance and DC resistance values against the official Eaton datasheet prior to integration. Confirm that the 0402 package dimensions align with the target PCB land pattern. Ensure the 450mA current rating meets the operational requirements of the specific circuit application to prevent saturation or excessive heating during use.

Selection Notes

Select this component when space constraints require a 0402 form factor for EMI suppression. The 70 Ohm impedance at 100 MHz targets specific noise frequencies common in digital circuits. Consider the 450mA current handling capability relative to the signal path load. Verify compatibility with standard reflow soldering profiles for surface-mount assembly processes.

Part Context

This part belongs to the MFBW1V series of multilayer ferrite beads manufactured by Eaton Electronics Division. The series utilizes proprietary multilayer technology to achieve high performance in small packages. The MFBW1V1005 variant specifically denotes the 0402 size code within this product family, offering a balance between physical size and electrical performance for modern electronic designs.

Replacement Considerations

Cross-reference with other Eaton MFBW1V1005 variants having different impedance values if the noise spectrum differs. Verify equivalent components from other manufacturers only if they match the 0402 package, 70 Ohm impedance, and 450mA current rating specifications exactly.
