MFBM1V2012-151-R

Overview

The MFBM1V2012-151-R is a multilayer chip ferrite bead manufactured by Eaton Electronics. It features an 0805 (2012 metric) surface-mount package with dimensions of 2.0 mm length, 1.2 mm width, and 1.2 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 80 mOhms. The device operates within a temperature range of -40°C to +85°C.

Feature Summary

• Multilayer construction for compact high-density circuit integration
• Shielded design to minimize electromagnetic interference
• High current handling capability suitable for power line filtering

Applications

• Power supply output filtering
• Clock signal noise suppression
• Data line EMI reduction in portable devices

Procurement Notes

Verify the specific impedance value and current rating against the official Eaton datasheet before finalizing procurement. Confirm that the 0805 package dimensions align with the target PCB footprint. Ensure the operating temperature range meets the environmental requirements of the end application. Cross-reference the manufacturer part number to avoid confusion with similar series components.

Selection Notes

Select this component when a balance between high current capacity and moderate impedance is required in a small form factor. The 2.5 A rating allows use in power rails where lower-current beads would saturate. The 150 Ohm impedance at 100 MHz targets common noise frequencies found in digital circuits. Consider the low DC resistance to minimize voltage drop and power loss in the circuit path.

Part Context

This part belongs to the MFBM1V series of multilayer chip ferrite beads from Eaton Electronics. The series offers various impedance and current ratings across different package sizes, including 0402, 0603, and 1206. The MFBM1V2012 variant specifically addresses applications needing higher current handling than smaller packages while maintaining a compact footprint compared to larger 1206 or 1210 options.

Replacement Considerations

Check for direct substitutes such as the MFBM1V2012-101-R or MFBM1V2012-181-R if impedance adjustments are permissible. Verify that any replacement maintains the same 0805 package size and current rating to ensure mechanical and electrical compatibility without redesigning the PCB layout.
