MFBM1V3216-300-R

Overview

The MFBM1V3216-300-R is a single-line multilayer ferrite chip bead designed for EMI suppression in power line applications. Manufactured by Eaton Electronics Division, this component utilizes a 1206 (3216 metric) surface-mount package with dimensions of 3.20mm x 1.60mm and a maximum height of 1.10mm. It exhibits an impedance of 30 Ohms at 100 MHz and supports a rated current of 6A. The device features a maximum DC resistance of 15 milliohms and operates within a temperature range of -40°C to +85°C.

Feature Summary

• Multilayer ferrite construction for effective electromagnetic interference suppression
• High current handling capability suitable for power line filtering
• Low DC resistance to minimize signal loss and power dissipation
• RoHS3 compliant and lead-free manufacturing

Applications

• Power line filtering in electronic circuits
• Electromagnetic interference suppression in high-current paths
• Signal integrity protection in compact surface-mount designs

Procurement Notes

Verify the specific impedance value and current rating against the official Eaton datasheet before integration. Confirm that the 1206 package dimensions align with the target PCB footprint. Ensure the operating temperature range meets the environmental requirements of the final assembly. Check for RoHS3 compliance status if required by regional regulations.

Selection Notes

Select this component when a low-impedance path is required alongside moderate noise attenuation at 100 MHz. The 6A rating makes it appropriate for power distribution networks where space is constrained. Compare against higher impedance variants if greater noise reduction is necessary, or lower current parts if thermal management is limited.

Part Context

This part belongs to the MFBM1V3216 series of multilayer ferrite chip beads from Eaton Electronics Division. The series offers various impedance options within the same 1206 package form factor, allowing designers to customize noise suppression characteristics without altering the board layout. It is distinct from RF inductors like the MCQ1V series due to its specific ferrite material properties for broadband EMI absorption.

Replacement Considerations

Direct substitutes include other MFBM1V3216 series variants with similar impedance ratings, such as the MFBM1V3216-310-R. Cross-brand replacements require matching the 1206 package size, 6A current rating, and 30 Ohm impedance at 100 MHz.
