Common Mode Chokes Procurement Notes

Verify the specific manufacturer designation when sourcing this part, as it appears in distributor catalogs under aliases such as MCI-2012-900-RU or associated with Mag Layers. Confirm availability status carefully, as some distributors list this item as discontinued or no longer available. Ensure the electrical parameters match the required 90 Ohms impedance and 370 mA current rating for the target application before finalizing procurement.

Common Mode Chokes Selection Notes

Select this component for applications requiring compact common mode chokes with low profile dimensions. The 2mm x 1.25mm footprint fits space-constrained designs. Verify that the 370 mA current handling capability meets the system's operational requirements. Consider the unshielded nature of the device when planning PCB layout to minimize electromagnetic interference coupling with nearby sensitive components.

Common Mode Chokes Part Context

This component belongs to the category of SMD common mode chokes used for EMI suppression. It serves as a passive filter element in electronic circuits. The part is distinct from power inductors or RF cables within the manufacturer's portfolio. Its primary function is noise reduction on differential data lines rather than energy storage or power conversion.

Common Mode Chokes Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Cross-reference with similar 90 Ohm, 2012 package common mode chokes if direct replacement is needed.
