MFBM1V3216-102-R

Overview

The Eaton MFBM1V3216-102-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 0.9 mm height. The component provides an impedance of 1 kOhm at a test frequency of 100 MHz with a tolerance of 25%. It supports a maximum DC current of 2.0 A and has a maximum DC resistance of 250 mOhms. The device operates within a temperature range of -40°C to +85°C.

Feature Summary

• Multilayer construction for effective electromagnetic interference suppression
• Shielded design to contain magnetic fields
• Surface-mount termination for automated assembly

Applications

• General-purpose EMI filtering in electronic circuits
• Power line noise suppression
• Signal integrity protection in high-speed digital systems

Procurement Notes

Verify the specific suffix 'R' indicates reel packaging when ordering. Confirm the impedance value corresponds to the required noise suppression profile for the target frequency. Ensure the 2.0 A current rating meets the circuit's operational requirements to prevent saturation. Check RoHS compliance documentation if environmental regulations apply to the final product assembly.

Selection Notes

Select this component when a 1 kOhm impedance at 100 MHz is required for noise attenuation. The 2.0 A current handling capability makes it suitable for power lines where higher currents are present compared to smaller packages. The 1206 footprint allows for standard SMT placement on most PCB layouts. Consider the 250 mOhm DCR impact on voltage drop if efficiency is critical.

Part Context

This part belongs to the Eaton MFB series of multilayer ferrite beads. The series offers various impedance values and current ratings in standardized package sizes. The MFBM1V3216 variant specifically targets applications requiring robust EMI suppression in compact spaces. It complements other components in the same family that offer different impedance characteristics for diverse filtering needs.

Replacement Considerations

Direct substitutes include other Eaton MFBM1V3216 variants with similar impedance and current ratings. Cross-brand replacements must match the 1206 footprint, 1 kOhm impedance, and 2.0 A current capacity. Verify thermal performance and mounting compatibility before substitution.
