Arrays, Signal Transformers Procurement Notes

Verify the manufacturer designation as Eaton Electronics Division or Cooper Industries/Coiltronics legacy branding. Confirm RoHS compliance status and specific datasheet revision. Ensure the part number suffix matches the required packaging format. Cross-reference electrical parameters against official Eaton documentation to avoid confusion with similar OCTA-PAC variants.

Arrays, Signal Transformers Selection Notes

Select this component for applications requiring high current handling up to 9 A with low DC resistance. The 2.18 µH inductance value suits specific coupling requirements. Verify thermal performance within the -40°C to 85°C operating range. Consider the physical dimensions of 11.43 mm x 11.43 mm x 6.35 mm for PCB layout constraints.

Arrays, Signal Transformers Part Context

This part belongs to the OCTA-PAC PLUS series of toroidal power inductors. It is functionally related to other models like CTX5-4A-R and CTX8-4A-R within the same family, differing primarily in inductance and current ratings. The series is characterized by amorphous metal cores and SMD mounting options.

Arrays, Signal Transformers Replacement Considerations

Direct substitutes include CTX5-4A-R and CTX8-4A-R from the same OCTA-PAC PLUS series, though inductance and current values differ. Legacy equivalents may exist under Coiltronics or Cooper Industries branding.
