Common Mode Chokes Procurement Notes
Verify the specific suffix XQ2L against official Murata documentation to confirm packaging configuration and tape-and-reel specifications. Ensure the selected variant matches the required impedance tolerance and current rating for the target application environment. Cross-reference the part number with the latest datasheet revision to confirm compliance with RoHS directives and material declarations before finalizing procurement orders.
Common Mode Chokes Selection Notes
Select this component when a 390 Ohm impedance at 100 MHz is required for common mode noise reduction in automotive systems. The 300 mA current rating must align with the operational load of the protected circuit. Consider the 0805 package dimensions for board space constraints and verify that the +125°C maximum operating temperature meets the thermal requirements of the installation location.
Common Mode Chokes Part Context
This component is part of the EMIFIL DLW21_H series, designed specifically for automotive electronics. The series utilizes Murata's proprietary POWRTRN technology to achieve high performance in small packages. These chokes are engineered to suppress electromagnetic interference while maintaining signal integrity in demanding automotive environments.
