MFBM1V1005-090-R

Overview

The MFBM1V1005-090-R is a multilayer chip ferrite bead manufactured by Eaton Electronics. It features a 0402 (1005 metric) surface-mount package with dimensions of 1 mm length, 0.5 mm width, and 0.5 mm height. The component provides an impedance of 9 Ohms at a test frequency of 100 MHz, with a tolerance range of 5 to 13 Ohms. It supports a maximum DC current of 1.8 A and has a maximum DC resistance of 50 mOhms. The device operates within a temperature range of -40°C to +85°C.

Feature Summary

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

Applications

• Power line noise suppression in electronic circuits
• Signal integrity enhancement in high-speed data lines
• Electromagnetic interference filtering in portable devices

Procurement Notes

Verify the specific impedance tolerance and current ratings against the official Eaton datasheet before integration. Confirm that the 0402 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 components.

Selection Notes

Select this component when space constraints require a 0402 footprint for ferrite bead applications. Consider the 1.8 A current rating to ensure adequate headroom for the specific circuit load. Evaluate the 9 Ohm impedance at 100 MHz to confirm effectiveness against the targeted noise frequencies. Verify compatibility with standard SMT reflow processes for reliable soldering.

Part Context

This part belongs to the MFBM1V series of multilayer chip ferrite beads from Eaton Electronics. The series is designed for general-purpose noise suppression in compact electronic designs. The 0402 package size allows for high-density board layouts. The product falls under the broader category of passive components used for EMI control.

Replacement Considerations

Consult Eaton documentation for direct cross-references. Verify that any substitute maintains the 0402 footprint and 1.8 A current handling. Ensure the replacement offers comparable impedance characteristics at 100 MHz.
