MFBW1V3216-310-R

Overview

The Eaton MFBW1V3216-310-R is a multilayer chip ferrite bead in a 1206 (3216 metric) surface-mount package. It provides an impedance of 31 ohms at a test frequency of 100 MHz with a maximum DC current rating of 3.0 A. The component features a shielded design and a low maximum DC resistance of 70 milliohms. It operates within a temperature range of -40°C to +85°C and has a tolerance of 25%. The unit weighs approximately 23 mg.

Feature Summary

• Shielded multilayer construction for electromagnetic interference suppression
• High current handling capability suitable for power line filtering
• Low DC resistance to minimize signal loss and power dissipation

Applications

• Power supply output filtering
• Data line noise suppression
• General-purpose EMI/RFI attenuation in electronic circuits

Procurement Notes

Verify the specific suffix 'R' indicates reel packaging when ordering. Confirm the impedance value of 31 ohms matches the target noise frequency spectrum. Ensure the 3.0 A current rating exceeds the maximum operating current of the application circuit to prevent saturation or overheating during normal operation.

Selection Notes

Select this component when a balance between high current capacity and moderate impedance is required. The 1206 footprint allows for standard SMT assembly processes. Compare against the MFBM1V series if higher current ratings are needed, or the MFBW1V-182 variant if higher impedance is necessary for different noise profiles.

Part Context

This part belongs to the MFBW1V series of multilayer ferrite beads from Eaton Electronics. These components are designed for general-purpose noise suppression in compact electronic devices. The series offers various impedance and current combinations within standardized package sizes to facilitate design flexibility across different product lines.

Replacement Considerations

Direct substitutes include other 1206 ferrite beads with similar 31 ohm impedance and 3A current ratings. Verify that any replacement maintains the same shielded characteristics and thermal performance limits.
