MFBW1V3216-090-R

Overview

The Eaton MFBW1V3216-090-R is a multilayer chip ferrite bead in a 1206 (3216 metric) surface-mount package. It provides an impedance of 9 Ohms at a test frequency of 100 MHz, with a tolerance range of 5 to 13 Ohms. The component supports a maximum DC current of 4 A and has a maximum DC resistance of 50 mOhms. It operates within a temperature range of -40°C to +85°C. Physical dimensions are 3.2 mm length, 1.6 mm width, and 0.9 mm height.

Feature Summary

• Multilayer construction for high-current applications
• Shielded design to minimize electromagnetic interference
• Surface-mount termination for automated assembly

Applications

• Power line filtering in electronic circuits
• Signal integrity management in high-speed data lines
• Electromagnetic interference suppression in consumer electronics

Procurement Notes

Verify the specific impedance tolerance and DC current rating against the official Eaton Electronics datasheet before integration. Confirm that the 1206 footprint matches the target PCB layout. Ensure the operating temperature range meets the environmental requirements of the final application. Cross-reference the manufacturer part number to avoid confusion with similar series components.

Selection Notes

Select this component when a 9 Ohm impedance at 100 MHz is required for noise suppression. The 4 A current rating makes it suitable for power rails where higher currents than standard beads can handle. The shielded feature is critical if crosstalk or external field susceptibility is a concern. Verify that the low DC resistance does not cause excessive voltage drop in the specific circuit design.

Part Context

This part belongs to the MFBW1V series of multilayer ferrite beads from Eaton Electronics. These components are designed for general-purpose EMI suppression in compact electronic devices. The series offers various impedance values and current ratings within the same 1206 footprint, allowing for flexible design choices without changing the board layout.

Replacement Considerations

Direct substitutes include other Eaton MFBW1V3216 variants with similar impedance and current ratings, such as MFBW1V3216-070-R or MFBW1V3216-101-R, provided their electrical characteristics align with the circuit requirements.
