MFBM1V3216-310-R

Overview

The Eaton MFBM1V3216-310-R is a multilayer chip ferrite bead designed for surface-mount technology applications. It operates within a temperature range of -40°C to +85°C and 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 31 Ohms at a test frequency of 100 MHz with a tolerance of ±25%. It supports a maximum DC current of 4.0 A and has a maximum DC resistance of 25 mOhms. The device is shielded and contains two elements in a single channel configuration.

Feature Summary

• Multilayer construction for effective electromagnetic interference suppression
• Shielded design to contain magnetic fields
• High current handling capability suitable for power line filtering

Applications

• Power supply output filtering
• DC-DC converter noise suppression
• General-purpose EMI suppression in electronic circuits

Procurement Notes

Verify the specific suffix 'R' indicates reel packaging when ordering. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure the selected variant matches the required impedance and current ratings for the target application circuit to avoid performance deviations.

Selection Notes

Select this component when a 1206 footprint is required with high current capacity. The 31 Ohm impedance at 100 MHz targets specific noise frequencies. Compare against the MFBW1V series if lower current ratings are acceptable for cost optimization. Verify thermal management requirements as self-heating occurs under load.

Part Context

This part belongs to the Eaton MFBM1V series of multilayer ferrite beads. These components are engineered for compact PCB layouts requiring robust noise attenuation. The series offers various impedance values tailored for different frequency suppression needs while maintaining standard SMD package dimensions for automated assembly compatibility.

Replacement Considerations

Direct substitutes include other Eaton MFBM1V3216 variants with identical impedance but different current ratings, such as MFBW1V3216-310-R. Cross-brand replacements require matching impedance, current rating, and physical dimensions.
