MFBM1V3216-800-R

Overview

The MFBM1V3216-800-R is a multilayer chip ferrite bead manufactured by Eaton Electronics. It features a 1206 (3216 metric) surface-mount package with dimensions of 3.2 mm length, 1.6 mm width, and 0.9 mm height. The component provides an impedance of 80 Ohms at a test frequency of 100 MHz. It supports a maximum DC current of 4.0 A and has a maximum DC resistance of 35 mOhms. The device operates within a temperature range of -40°C to +85°C and includes shielding.

Feature Summary

• Multilayer chip construction for compact surface-mount integration
• Shielded design to minimize electromagnetic interference
• High current handling capability suitable for power line filtering

Applications

• Power line noise suppression in electronic circuits
• Electromagnetic interference (EMI) filtering
• Signal integrity protection in high-current applications

Procurement Notes

Verify the specific impedance value and current rating against the official Eaton datasheet before procurement. Confirm that the 1206 package dimensions and shielding characteristics align with the target PCB layout requirements. Ensure compatibility with the intended operating temperature range of -40°C to +85°C for the specific application environment.

Selection Notes

Select this component when a low DC resistance and high current capacity are required for EMI suppression. The 80 Ohm impedance at 100 MHz targets specific noise frequencies. Compare against other series members like the MFBM1V3216-801-R if higher impedance or lower current ratings are acceptable for the design constraints.

Part Context

This part belongs to the MFBM1V series of multilayer ferrite beads from Eaton Electronics. It shares the standard 1206 footprint with variants offering different impedance values such as 300 Ohms or 800 Ohms. The series is designed for general-purpose noise suppression in consumer and industrial electronics requiring reliable surface-mount solutions.

Replacement Considerations

Direct substitutes include other Eaton MFBM1V3216 series parts with similar electrical characteristics. Verify impedance tolerance and current ratings when considering alternatives from other manufacturers to ensure equivalent performance in the specific circuit application.
