MFBM1V3216-221-R

Overview

The MFBM1V3216-221-R is a surface-mount ferrite bead manufactured by Eaton Electronics Division. It features a 1206 (3216 Metric) package and provides an impedance of 220 Ohms at 100 MHz. The component supports a maximum current rating of 3 Amperes with a low DC resistance of 55 milliohms. Designed for power line applications, it offers single-line noise suppression in a compact form factor suitable for space-constrained electronic assemblies.

Feature Summary

• Provides effective high-frequency noise attenuation on power lines
• Features a robust 3A current handling capability
• Utilizes a standard 1206 surface-mount footprint

Applications

• Power line filtering in portable electronics
• Noise suppression in consumer device power inputs
• EMI reduction in automotive infotainment systems

Procurement Notes

Verify the specific manufacturer part number against official Eaton documentation to ensure compatibility with design requirements. Confirm that the 1206 package dimensions and thermal characteristics align with the target PCB layout. Ensure compliance with relevant environmental standards such as RoHS if required by the end application specifications.

Selection Notes

Select this component when a 220 Ohm impedance at 100 MHz is required for power rail filtering. The 3A current rating makes it suitable for higher-power sections compared to lower-current variants. Consider the 55 milliohm DC resistance impact on voltage drop within the circuit design constraints.

Part Context

This ferrite bead belongs to Eaton's MFBM series, which focuses on multi-high current performance in small packages. The 3216 metric size balances physical footprint with electrical performance, offering a solution between smaller signal-grade beads and larger power chokes.

Replacement Considerations

Cross-reference with other Eaton MFBM series parts or equivalent 1206 ferrite beads from other manufacturers. Verify that substitute components match the 220 Ohm impedance, 3A current rating, and 55 milliohm resistance specifications.
