MFBW1V1005-101-R

Overview

The MFBW1V1005-101-R is a multilayer chip ferrite bead from Eaton Electronics, designed for EMI suppression in surface-mount applications. It features a 0402 (1005 metric) package with dimensions of 1.0 mm length, 0.5 mm width, and 0.5 mm height. The component provides an impedance of 100 Ohms at a test frequency of 100 MHz with a tolerance of ±25%. It supports a maximum DC current of 450 mA and has a maximum DC resistance of 0.20 Ohms. 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 contain magnetic fields
• Single-channel configuration for compact circuit integration

Applications

• Portable electronic devices requiring space-constrained filtering
• Data line protection in high-speed digital circuits
• Power supply input filtering for low-current applications

Procurement Notes

Verify the specific suffix 'R' indicates reel packaging when ordering. Confirm RoHS compliance status as environmental certifications may have expiration dates or updates. Ensure the 0402 footprint matches the target PCB layout constraints. Validate that the 450 mA current rating meets the operational requirements of the specific circuit path to prevent saturation.

Selection Notes

Select this component when a 100 Ohm impedance at 100 MHz is required for noise attenuation. The 0402 size is suitable for dense board layouts where larger ferrites cannot fit. Consider the 450 mA current limit to ensure the component does not exceed its thermal or magnetic saturation limits during normal operation. Compare against other series members if higher current handling or different impedance values are needed.

Part Context

This part belongs to the MFBW1V series of multilayer ferrite beads from Eaton Electronics. The series offers various impedance and current ratings across different package sizes, including 0402, 0603, and 1206 footprints. The W1V designation typically denotes specific material characteristics optimized for high-frequency noise suppression in consumer electronics.

Replacement Considerations

Cross-reference with MFBM1V1005-101-R for similar impedance but potentially different current handling characteristics. Verify pinout compatibility and physical dimensions before substituting with components from other manufacturers.
