MFBM1V1608-221-R

Overview

The Eaton MFBM1V1608-221-R is a multilayer chip ferrite bead in a 0603 (1608 metric) SMD package. It provides an impedance of 220 Ohms at a test frequency of 100 MHz with a tolerance of ±25%. The component supports a maximum DC current of 1.5 A and has a maximum DC resistance of 120 mOhms. It operates within a temperature range of -40°C to +85°C.

Feature Summary

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

Applications

• Power line noise suppression in electronic circuits
• EMI filtering for high-current signal paths
• Component protection in automotive electronics

Procurement Notes

Verify the specific impedance value and current rating against the official Eaton datasheet before procurement. Confirm that the 0603 package dimensions align with the PCB footprint requirements. Ensure the operating temperature range meets the environmental conditions of the final assembly. Check RoHS compliance status if required by the manufacturing process.

Selection Notes

Select this component when a low-profile, high-current ferrite bead is needed for EMI suppression. The 1.5 A rating distinguishes it from lower-current variants in the same series. Consider the 120 mOhms DC resistance impact on voltage drop in sensitive power rails. The 0603 size offers a balance between current capacity and board space efficiency.

Part Context

This part belongs to the Eaton MFBM1V series of multilayer chip ferrite beads. The series includes various impedance values and current ratings within the 0603 package. It is designed for general-purpose EMI suppression in consumer, industrial, and automotive applications where space constraints are critical.

Replacement Considerations

Direct substitutes include other Eaton MFBM1V1608 variants with similar impedance and current ratings, such as MFBM1V1608-301-R, provided the impedance difference is acceptable for the circuit design. Cross-brand replacements require matching impedance, current rating, and package dimensions.
