MFBA3V1608C-221-R

Overview

The MFBA3V1608C-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. It supports a maximum DC current of 250 mA and has a maximum DC resistance of 600 mOhms. The device operates within a temperature range of -55°C to +150°C and holds AEC-Q200 qualification.

Feature Summary

• Automotive high impedance multilayer construction
• AEC-Q200 qualified for reliability
• Compact 0603 surface-mount footprint

Applications

• Automotive electronic circuit filtering
• High-frequency noise suppression in vehicle systems
• Power line protection in compact automotive modules

Procurement Notes

Verify the specific suffix 'C' against official Eaton documentation to confirm electrical characteristics, as suffixes may denote variations in impedance or current ratings. Ensure the source document explicitly lists the 250 mA rating and 600 mOhm resistance for this exact part number before procurement. Cross-reference the AEC-Q200 status with the manufacturer's latest datasheet to confirm current qualification status.

Selection Notes

Select this component when designing for automotive environments requiring robust noise suppression in space-constrained layouts. The 0603 package allows for dense PCB placement while maintaining high thermal stability up to 150°C. Consider the 250 mA current limit during circuit design to prevent saturation. Verify compatibility with reflow soldering profiles specified in the official data sheet.

Part Context

This ferrite bead belongs to the MFBA3 series from Eaton Electronics, designed specifically for automotive applications. The series utilizes multilayer technology to provide effective high-frequency attenuation. The 0603 form factor is standard for modern automotive electronics, balancing performance with board space efficiency. It serves as a critical passive component for signal integrity in noisy vehicle electrical systems.

Replacement Considerations

Consult Eaton's official substitution guide for verified equivalents. Generic ferrite beads may not meet AEC-Q200 automotive standards or the specific 220 Ohm @ 100 MHz impedance profile. Ensure any substitute matches the 0603 mechanical dimensions and thermal operating range.
