Common Mode Chokes Procurement Notes

Verify the specific suffix 'L' against official Murata documentation to confirm reel packaging specifications. Ensure the impedance value of 45 Ohms matches the target frequency requirements for the application. Confirm that the 100 mA current rating is sufficient for the operating conditions. Check RoHS compliance status via the manufacturer's datasheet before procurement.

Common Mode Chokes Selection Notes

Select this component when space constraints require a small SMD package like 0504 metric. The 45 Ohm impedance is suitable for frequencies around 100 MHz. Ensure the circuit current does not exceed 100 mA to prevent saturation. Verify that the 880 mOhms DC resistance meets the voltage drop requirements of the signal line.

Common Mode Chokes Part Context

This part belongs to the Murata EMIFIL DLM series of monolithic common mode chokes. These components are designed for noise suppression in portable electronic devices. The series offers various impedance values and current ratings to suit different signal integrity needs. The DLM11 variant specifically targets compact applications requiring efficient EMI reduction.

Common Mode Chokes Replacement Considerations

Consult Murata's official cross-reference tools for verified substitutes. Ensure any replacement maintains the 45 Ohm impedance at 100 MHz and 100 mA current rating. Verify package compatibility with existing PCB footprints.
