Common Mode Chokes Procurement Notes

Verify the specific datasheet version when sourcing this component to ensure compatibility with your circuit requirements. Confirm that the vertical package style matches your board layout constraints. Check for any updated regulatory compliance certifications if required for your target market. Ensure the 400mA current rating meets your system's operational needs without saturation.

Common Mode Chokes Selection Notes

Select this component when a vertical form factor is necessary for assembly or mechanical clearance reasons. Consider the 2.448 Ohm DCR limit to ensure it does not introduce excessive voltage drop in your power or signal lines. Evaluate the 400mA current handling capability against peak load conditions. Compare its impedance profile with alternative surface-mount options if space permits.

Common Mode Chokes Part Context

This part belongs to the ELF-18 series of common mode chokes from Panasonic. The series includes various models with different impedance and current ratings, such as ELF-18D616 and ELF-18D624F.
