Common Mode Chokes Procurement Notes

Verify the specific suffix MQ2K against official Murata documentation to confirm package type and tape/reel specifications. Ensure the ordering part number matches the required impedance and current ratings for your design. Cross-reference with authorized distributors to confirm availability and authenticity before finalizing procurement plans.

Common Mode Chokes Selection Notes

Select this component when automotive-grade reliability is required alongside compact SMD packaging. Compare the 1.5 A current rating and 1.1 kOhm impedance against system noise profiles. Verify that the 56 mOhm DCR meets power loss constraints. Confirm compatibility with automated assembly processes due to its surface mount form factor.

Common Mode Chokes Part Context

This component belongs to the DLW5ATH series of wirewound common mode chokes manufactured by Murata Electronics. The series is engineered for robust electromagnetic interference suppression in demanding environments. The DLW5ATH112MQ2K variant specifically targets applications requiring verified automotive compliance and stable performance across wide temperature ranges.

Common Mode Chokes Replacement Considerations

Check for direct substitutes within the DLW5ATZ or DLW5ATN series if pinout or dimensional tolerances differ. Verify that alternative parts maintain equivalent AEC-Q200 certification and impedance characteristics at 100 MHz to ensure functional parity.
