Common Mode Chokes Procurement Notes

Verify the specific package dimensions and terminal configuration against your PCB footprint library before ordering. Confirm that the thermal management requirements of your design accommodate the self-heating characteristics associated with a 20 A current rating. Ensure the selected mounting orientation aligns with the mechanical constraints of the enclosure. Cross-reference the impedance curve at your operating frequency to validate noise attenuation performance.

Common Mode Chokes Selection Notes

Select this component when designing circuits requiring robust common mode rejection at high current levels. The 120 µH inductance provides significant impedance at higher frequencies while maintaining low insertion loss for DC power transmission. Consider the physical size of the planar package relative to available board space. Evaluate the thermal dissipation needs given the low DCR and high current capacity.
