MFBM1V3216-181-R

Overview

The MFBM1V3216-181-R is a multilayer chip ferrite bead manufactured by Eaton Electronics. It features a shielded design in 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 180 Ohms at a test frequency of 100 MHz with a tolerance of ±25%. It supports a maximum DC current of 3 A and has a maximum DC resistance of 55 mOhms. The unit operates within a temperature range of -40°C to +85°C.

Feature Summary

• Shielded construction minimizes electromagnetic interference coupling
• Multilayer chip architecture for compact surface-mount integration
• High current handling capability suitable for power line filtering

Applications

• Power line noise suppression in electronic circuits
• EMI filtering for high-current signal paths
• Component protection in automotive electronics

Procurement Notes

Verify the specific impedance value and current rating against the official Eaton datasheet prior to ordering. Confirm that the 1206 package dimensions align with the target PCB footprint requirements. Ensure compliance with RoHS standards if required by the end application. Cross-reference the manufacturer part number to avoid confusion with similar series variants.

Selection Notes

Select this component when a shielded ferrite bead with a 180 Ohm impedance at 100 MHz is required for high-current applications up to 3 A. The 1206 package size offers a balance between current capacity and board space efficiency. Consider the low DC resistance of 55 mOhms to minimize voltage drop and power loss in the circuit path compared to higher resistance alternatives.

Part Context

This part belongs to the MFBM1V series of multilayer chip ferrite beads from Eaton Electronics. The series utilizes proprietary materials to provide effective noise absorption across a broad frequency spectrum. The MFBM1V3216 designation indicates the specific impedance and current characteristics within the standardized 1206 form factor family.

Replacement Considerations

Direct substitutes include other Eaton MFBM1V3216 series parts with matching 180 Ohm impedance and 3 A current ratings, such as MFBM1V3216-181-R equivalents from authorized distributors. Verify that any replacement maintains the shielded characteristic and identical 1206 package dimensions to ensure mechanical compatibility.
