MFBM1V1608-070-R

Overview

The MFBM1V1608-070-R is a multilayer chip ferrite bead manufactured by Eaton Electronics Division. It features a single-line power filter design housed in a 0603 (1608 metric) surface-mount package with dimensions of 1.6 mm length, 0.8 mm width, and 0.8 mm height. The component provides an impedance of 7 Ohms at a test frequency of 100 MHz and supports a maximum DC current of 6 A. Its maximum DC resistance is 20 mOhms, and it operates within a temperature range of -40°C to +85°C.

Feature Summary

• High current handling capability rated for up to 6 A
• Low DC resistance of 20 mOhms for minimal signal loss
• Shielded multilayer construction for EMI suppression

Applications

• Power line filtering in portable electronic devices
• EMI suppression on high-current data buses
• Noise reduction in automotive electronics systems

Procurement Notes

Verify the specific impedance tolerance and current rating against the official Eaton datasheet before integration. Confirm that the 0603 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 a low-impedance path is required alongside significant current capacity. The 7 Ohm impedance is suitable for suppressing lower-frequency noise while maintaining signal integrity. Compare the 6 A rating against peak load currents to prevent saturation. Consider the 0603 size constraint if space is limited compared to larger ferrite beads.

Part Context

This part belongs to the MFBM1V series of multilayer ferrite chips designed for EMI suppression. The series offers various impedance values tailored for different frequency ranges and current loads. Eaton utilizes proprietary materials to achieve stable performance across the specified temperature range. The MFBM1V1608-070-R specifically targets applications requiring robust current handling in compact form factors.

Replacement Considerations

Consult Eaton's official substitution guide for verified equivalents. Generic replacements may not match the specific permeability characteristics or current saturation limits.
