MFBW1V1608-221-R

Overview

The Eaton MFBW1V1608-221-R is a multilayer chip ferrite bead designed for surface-mount applications. It features a 0603 (1608 metric) package with dimensions of 1.6 mm length, 0.8 mm width, and 0.8 mm height. The component provides an impedance of 220 Ohms at a test frequency of 100 MHz. It supports a maximum DC current of 1 A and has a maximum DC resistance of 200 mOhms. The device operates within a temperature range of -40°C to +85°C.

Feature Summary

• Multilayer construction for compact surface-mount integration
• High impedance performance at 100 MHz for noise suppression
• Shielded design to contain electromagnetic interference

Applications

• Power supply line filtering in portable electronics
• Signal integrity management in high-speed digital circuits
• EMI suppression on data bus lines

Procurement Notes

Verify the specific impedance tolerance and current rating against the official Eaton datasheet before integration. Confirm that the 0603 footprint matches the target PCB layout constraints. 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 variants.

Selection Notes

Select this component when a 220 Ohm impedance at 100 MHz is required for a 1 Ampere circuit. The 0603 package size suits space-constrained designs. Consider the 200 mOhm DC resistance impact on power loss. Evaluate thermal performance within the specified -40°C to +85°C range. Compare against other ferrite beads if higher current capacity or different impedance characteristics are needed.

Part Context

This part belongs to the MFBW1V series of multilayer ferrite beads from Eaton Electronics Division. The series offers various impedance values and current ratings in standard footprints. The MFBW1V1608-221-R specifically targets applications requiring moderate current handling with significant high-frequency attenuation in a small form factor.

Replacement Considerations

Direct substitutes include other 0603 ferrite beads with 220 Ohms @ 100 MHz and 1A rating. Verify pin compatibility and impedance curves. Check if alternative manufacturers offer equivalent shielding and thermal specifications.
