Procurement Notes
Verify the specific part number suffix against the official Eaton datasheet to confirm impedance and tolerance specifications. Ensure that the procurement source provides valid traceability documentation required for automotive-grade components. Confirm that the delivered items match the AEC-Q200 qualification status specified in the product data sheet prior to integration into production lines.
Selection Notes
Select this component when designing circuits requiring common mode noise attenuation for CAN-BUS interfaces within automotive environments. The 120 Ohm impedance at 100 MHz provides effective filtering for high-frequency interference while maintaining signal integrity. Consider the 370 mA current rating and 300 mOhm DCR to ensure compatibility with the power budget and thermal constraints of the target application circuit.
Part Context
This component belongs to the Eaton ACE series of automotive common mode chip inductors. The series offers various impedance options tailored for different bus speeds and noise profiles. The ACE1V2012 variant specifically targets compact board designs, providing reliable electromagnetic interference suppression for critical vehicle communication networks under strict automotive reliability standards.
Replacement Considerations
Consult Eaton's official cross-reference tools or datasheets for verified substitutes. Direct replacements must maintain identical AEC-Q200 qualification, 0805 package dimensions, and 120 Ohm @ 100 MHz impedance characteristics to ensure functional equivalence in existing automotive designs.
