Procurement Notes
Verify the specific datasheet version to confirm RoHS compliance status and lead-free characteristics. Ensure that the through-hole footprint matches the target PCB design specifications regarding pad size and spacing. Confirm that the 22mH inductance value aligns with the system's impedance matching requirements. Check for any obsolete status notifications from the manufacturer, as this part may have limited availability or replacement recommendations.
Selection Notes
Select this component when designing systems requiring precise isolation for ISDN S-interface signals. The 1CT:2CT winding ratio must match the transformer requirements of the connected interface circuitry. Consider the physical envelope constraints, as the through-hole package occupies specific board area. Validate that the operating temperature range meets the environmental conditions of the final application. Ensure compatibility with the signal frequency spectrum defined by ISDN standards.
Part Context
This component belongs to the Pulse Electronics audio and signal transformer family, which includes various transformers for telecommunications and data interface applications. It is distinct from current sense transformers like the PE-64978NL, serving instead as an isolation device for digital signal transmission. The product line focuses on providing reliable electromagnetic interference rejection and signal integrity in sensitive communication interfaces.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation. Users should consult official distributor channels for potential obsolescence notices or manufacturer-recommended alternatives if this specific model becomes unavailable.
