MFBW1V1005-000-R

Overview

The MFBW1V1005-000-R is a multilayer ferrite chip bead manufactured by Eaton Electronics Division. It features a 0402 (1005 metric) surface-mount package with dimensions of 1.00mm length, 0.50mm width, and 0.65mm maximum height. The component provides zero ohms impedance at 10 MHz and supports a maximum DC current of 1.8A. It has a maximum DC resistance of 50 milliohms and operates within a temperature range of -40°C to +85°C.

Feature Summary

• Multilayer construction for effective EMI suppression in compact designs
• Zero ohm impedance configuration suitable for jumper applications or specific filtering requirements
• Surface mount design optimized for automated assembly processes

Applications

• EMI suppression in portable electronic devices
• Jumper replacement in power supply circuits
• Signal integrity management in high-speed digital interfaces

Procurement Notes

Verify the exact impedance specification against the datasheet, as zero-ohm variants may serve distinct functional roles compared to standard ferrite beads. Confirm package compatibility with PCB footprint requirements. Ensure environmental compliance documentation matches project specifications. Validate thermal performance under maximum load conditions before final integration.

Selection Notes

Select this component when a zero-ohm path or specific low-frequency filtering characteristic is required in a 0402 footprint. Consider the 1.8A current rating for power line applications. Evaluate the low DC resistance to minimize voltage drop. Compare against other series members if higher impedance values are needed for different frequency ranges.

Part Context

This part belongs to the MFBW1V series of multilayer ferrite chip beads from Eaton Electronics. The series offers various impedance options within the same physical footprint family. These components are designed for general-purpose EMI suppression in consumer electronics and industrial equipment where space constraints are critical.

Replacement Considerations

Direct substitutes include other Eaton MFBW1V1005 variants with matching impedance ratings. Cross-brand replacements require verification of footprint, current rating, and impedance characteristics. Ensure equivalent thermal and electrical performance metrics are met during substitution.
