• Automotive-grade reliability certified under the AEC-Q200 standard for harsh environment durability
• Low DC resistance design minimizes power loss and voltage drop within the signal path

Applications

• High-speed data line protection in automotive infotainment systems
• Noise suppression on USB and HDMI interfaces in vehicle electronics
• Power rail filtering for sensitive microcontroller units in automotive modules

Procurement Notes

Verify the specific suffix K against the manufacturer's official datasheet to confirm package dimensions and termination style. Ensure the selected variant meets the required AEC-Q200 certification level for your specific application environment. Cross-reference the impedance tolerance and current ratings with your circuit design specifications before finalizing procurement orders.

Selection Notes

Select this component when designing for automotive applications requiring robust EMI suppression on high-speed digital lines. The 220 Ohm impedance value is suitable for attenuating noise in the 100 MHz range without significantly affecting signal integrity. Consider the 750 mA current rating to ensure adequate headroom for peak load conditions during operation.

Part Context

This ferrite bead belongs to the MFBA3V2012 series, which consists of small-footprint components optimized for dense PCB layouts. The series is engineered specifically for the automotive sector, offering consistent performance across wide temperature ranges. It serves as a critical passive element for maintaining signal quality in modern vehicle electronic architectures.

Replacement Considerations

Consult Eaton Electronics documentation for direct cross-references. Verify that any substitute part matches the 220 Ohm impedance at 100 MHz, 750 mA current rating, and 300 mOhm DCR. Ensure the replacement also holds AEC-Q200 certification if automotive compliance is mandatory.
