MFBW1V1608-181-R

Overview

The Eaton MFBW1V1608-181-R is a shielded multilayer ferrite chip bead designed for surface-mount technology in the 0603 (1608 metric) package. It provides an impedance of 180 Ohms at a test frequency of 100 MHz with a tolerance of ±25%. The component supports a maximum DC current of 1 A and has a maximum DC resistance of 200 mOhms. It operates within a temperature range of -40°C to +85°C, featuring physical dimensions of 1.6 mm length, 0.8 mm width, and 0.8 mm height.

Feature Summary

• Shielded multilayer construction for effective EMI suppression
• High current handling capability up to 1 A
• Compact 0603 surface-mount footprint

Applications

• General EMI noise filtering in electronic circuits
• Signal line protection in consumer electronics
• Power supply output filtering

Procurement Notes

Verify the specific suffix 'R' corresponds to the required packaging format, such as cut tape or reel, as indicated by distributor listings. Confirm RoHS compliance status through official documentation before integration. Ensure the 1A current rating aligns with the circuit's operational requirements to prevent saturation. Cross-reference the 180 Ohm impedance value at 100 MHz against the target noise spectrum.

Selection Notes

Select this component when a shielded ferrite bead is required to minimize magnetic interference with adjacent traces. The 0603 size offers a balance between impedance performance and board space efficiency. The 1A current rating suits moderate power applications. Verify that the 200 mOhms DC resistance meets voltage drop constraints in the signal path.

Part Context

This part belongs to the Eaton MFBW1V series of multilayer chip beads. These components are engineered for high-density PCB layouts where space is limited. The series utilizes advanced ceramic materials to achieve stable impedance characteristics across the specified temperature range. It serves as a passive filter element in modern electronic assemblies.

Replacement Considerations

Direct substitutes include other 0603 ferrite beads with similar 180 Ohm impedance and 1A current ratings. Check manufacturer datasheets for equivalent electrical parameters and thermal characteristics. Ensure mechanical compatibility with existing footprints.
