MFBM1V3216-700-R

Overview

The Eaton MFBM1V3216-700-R is a multilayer ferrite chip bead designed for EMI suppression in surface-mount applications. It features a 1206 (3216 metric) package with dimensions of 3.2 mm length, 1.6 mm width, and 1.10 mm height. The component provides an impedance of 70 Ohms at a test frequency of 100 MHz with a tolerance of ±25%. It supports a maximum DC current of 4 A and has a maximum DC resistance of 35 mOhms. The operating temperature range spans from -40°C to +85°C.

Feature Summary

• Multilayer construction for effective electromagnetic interference suppression
• High current handling capability suitable for power line filtering
• Shielded design to minimize external magnetic field interaction

Applications

• Power supply output filtering
• DC/DC converter noise suppression
• General-purpose EMI filtering on high-current signal lines

Procurement Notes

Verify the specific suffix against official Eaton documentation to confirm electrical characteristics, as variations may exist within the series. Ensure the procurement channel provides valid RoHS compliance certificates and original manufacturer traceability. Cross-reference the part number with the latest datasheet to confirm availability status and lead times prior to finalizing orders.

Selection Notes

Select this component when a 1206 footprint is required for high-current applications needing 70 Ohms attenuation at 100 MHz. The 4 A rating distinguishes it from lower-current variants in the same series. Consider the 35 mOhm DCR for voltage drop calculations in power-sensitive circuits. Verify thermal performance within the specified -40°C to +85°C range for the target environment.

Part Context

This part belongs to the Eaton MFBM1V series of multilayer ferrite beads. These components are engineered for compact PCB layouts while providing robust noise suppression. The MFBM1V series typically offers higher current ratings compared to standard signal-line ferrites, making them suitable for power integrity management in modern electronic devices.

Replacement Considerations

Public confirmed substitutes include MFBW1V3216-700-R, which shares the 1206 package and 70 Ohm impedance but differs in current rating and DC resistance specifications.
