Procurement Notes

Verify the specific suffix (e.g., T vs NL) as it denotes distinct pinout or electrical variations. Confirm RoHS compliance status directly from the manufacturer datasheet, as some sources indicate non-compliance for certain variants. Ensure the selected part matches the required isolation voltage and leakage inductance specifications for the target circuit design.

Selection Notes

Select this component when a quad-port pulse transformer is required for T1/E1 digital telephony interfaces. Evaluate the 1.2mH inductance against the circuit's impedance matching requirements. Consider the surface mount footprint compatibility with the PCB layout constraints and ensure the operating temperature range meets the environmental specifications of the deployment site.

Part Context

This component belongs to the Pulse Transformers category within Pulse Electronics' portfolio. It serves as a critical passive element in digital telecommunications hardware, facilitating signal coupling and isolation between integrated circuits and line drivers in standard telephone network infrastructure.

Replacement Considerations

The TX1266NL is a documented variant within the same product family. Verify pin compatibility and electrical parameters before substitution, as suffix differences may indicate changes in packaging or specific performance characteristics.
