MFBW1V3216-151-R

Overview

The MFBW1V3216-151-R is a multilayer chip ferrite bead manufactured by Eaton Electronics. It features a shielded design in 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 150 Ohms at a test frequency of 100 MHz with a tolerance of ±25%. It supports a maximum DC current of 2.5 A and has a maximum DC resistance of 120 mOhms. The device operates within a temperature range of -40°C to +85°C.

Feature Summary

• Shielded construction minimizes electromagnetic interference coupling
• Multilayer chip architecture for compact surface-mount integration
• High current handling capability suitable for power line filtering

Applications

• Power supply output filtering
• DC-DC converter noise suppression
• High-speed data line protection

Procurement Notes

Verify the specific impedance value and current rating against the official Eaton datasheet before procurement. Confirm that the 1206 package dimensions align with the target PCB footprint. Ensure the operating temperature range meets the environmental requirements of the final assembly. Cross-reference the manufacturer part number to avoid confusion with similar series variants.

Selection Notes

Select this component when a shielded ferrite bead is required for high-current applications up to 2.5 A. The 150 Ohm impedance at 100 MHz makes it suitable for suppressing mid-frequency noise. Consider the low DC resistance of 120 mOhms to minimize voltage drop and power loss in the circuit path compared to higher impedance alternatives.

Part Context

This part belongs to the MFBW1V3216 series of multilayer chip ferrite beads from Eaton Electronics. The series offers various impedance and current ratings within the standard 1206 package. These components are designed for general-purpose EMI suppression in electronic circuits requiring reliable performance in compact form factors.

Replacement Considerations

Compatible substitutes include other 1206 shielded ferrite beads with similar 150 Ohm impedance and >2.5 A current ratings. Verify pin compatibility and thermal characteristics when replacing. Consult Eaton documentation for direct cross-references or equivalent specifications from other manufacturers.
