MFBM1V3216-500-R

Overview

The MFBM1V3216-500-R is a multilayer chip ferrite bead manufactured by Eaton - Electronics Division. It features a 1206 (3216 metric) surface-mount package with dimensions of 3.2 mm length, 1.6 mm width, and 0.9 mm maximum height. The component provides an impedance of 50 Ohms at 100 MHz and supports a maximum DC current of 6.0 A. Its maximum DC resistance is specified as 10 mOhms. The device operates within a temperature range of -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 attenuation
• General EMI suppression in electronic circuits

Procurement Notes

Verify the manufacturer part number MFBM1V3216-500-R against official Eaton documentation to confirm specifications. Ensure the procurement source provides valid RoHS compliance certificates. Confirm that the delivered components match the 1206 package dimensions and electrical ratings defined in the datasheet before integration into production.

Selection Notes

Select this component when high current capacity is required alongside moderate impedance values. The 6.0 A rating distinguishes it from lower-current variants in the series. Verify that the 50 Ohm impedance at 100 MHz aligns with the target noise frequency spectrum. Ensure the PCB footprint accommodates the 3.2 mm x 1.6 mm outline.

Part Context

This ferrite bead belongs to the MFBM1V series, which focuses on high-current applications. It complements other series like MFBW1V, which typically offer different current and impedance profiles. The 1206 package size allows for compact placement on standard PCB layouts while maintaining robust thermal and electrical performance.

Replacement Considerations

Cross-reference with MFBM1V3216-050-R for higher current options or MFBM1V3216-121-R for different impedance characteristics. Verify compatibility with existing board space and thermal constraints before substitution.
