MFBA3V1608K-221-R

Overview

The MFBA3V1608K-221-R is an automotive-grade multilayer chip ferrite bead manufactured by Eaton Electronics. It features 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 220 Ohms at a test frequency of 100 MHz and supports a maximum DC current of 0.55 A. It operates within a temperature range of -55°C to +150°C.

Feature Summary

• Automotive high impedance multilayer construction
• SMD/SMT termination for PCB mounting
• Wide operating temperature capability

Applications

• High-frequency EMI suppression in automotive circuits
• Signal line filtering in vehicle electronics
• Power supply noise attenuation

Procurement Notes

Verify the specific suffix 'K' against official Eaton documentation to confirm if it denotes a specific tape-and-reel configuration or packaging variant distinct from standard reels. Confirm RoHS compliance status through the manufacturer's datasheet rather than distributor summaries. Ensure the ordering quantity aligns with the factory pack size of 4000 units if bulk procurement is required.

Selection Notes

Select this component when a 0603 footprint is constrained but higher current handling than standard beads is needed. The 220 Ohm impedance at 100 MHz targets common automotive noise frequencies. Verify that the 0.55 A current rating exceeds the peak operational current of the target circuit to prevent saturation. Ensure the PCB layout accommodates the 1.6 x 0.8 mm physical dimensions.

Part Context

This part belongs to the MFBA3 series of automotive ferrite beads designed for high-impedance applications. It complements other Eaton components like the MFBA2V series, offering similar form factors but potentially different electrical characteristics tailored for specific automotive noise profiles and reliability standards.

Replacement Considerations

Direct substitutes include MFBA3V1608K-151-R (150 Ohms) and MFBA3V1608K-471-R (470 Ohms). Cross-reference impedance curves to ensure compatibility with the target noise spectrum.
