MFBW1V3216-050-R

Overview

The MFBW1V3216-050-R is a shielded multilayer chip ferrite bead from the Eaton Electronics MFBW1V series. It features a 1206 (3216 metric) surface-mount package with dimensions of 3.2 mm length, 1.6 mm width, and 0.9 mm height. The component provides an impedance of 7 Ohms at a test frequency of 100 MHz and supports a maximum DC current of 4.0 A. Its maximum DC resistance is 40 mOhms, with an operating temperature range from -40°C to +85°C.

Feature Summary

• Shielded multilayer construction for effective electromagnetic interference suppression
• High current handling capability suitable for power line filtering applications
• Compact 1206 surface-mount footprint for space-constrained PCB designs

Applications

• Power supply output filtering in electronic devices
• Signal integrity enhancement on high-speed data lines
• Electromagnetic interference suppression in consumer electronics

Procurement Notes

Verify the specific impedance value against design requirements, as datasheet listings may vary between 5 Ohms and 7 Ohms depending on the source revision. Confirm the manufacturer part number matches the required tolerance and packaging format before ordering. Ensure compatibility with the target application's thermal and current specifications.

Selection Notes

Select this component when a shielded ferrite bead is required to minimize magnetic field radiation while maintaining low DC resistance. The 1206 package offers a balance between current capacity and board space. Consider the 4.0 A current rating to ensure adequate margin for peak load conditions without saturation.

Part Context

This part belongs to the Eaton MFBW1V series of multilayer chip beads. These components are designed for general-purpose noise suppression in digital and analog circuits. The series utilizes proprietary ceramic materials to achieve stable impedance characteristics across the specified temperature range.

Replacement Considerations

Cross-reference with other Eaton MFBW1V variants or equivalent shielded ferrite beads from other manufacturers that match the 1206 footprint, 4.0 A current rating, and similar impedance values.
