Procurement Notes
Verify the specific datasheet version corresponding to the TX1341NLT designation to confirm pinout compatibility and electrical tolerances. Ensure that the surface mount footprint matches the target PCB layout dimensions of 25.40mm by 7.87mm. Confirm that the isolation voltage rating meets the safety requirements of the intended telecommunications environment before finalizing procurement specifications.
Selection Notes
Select this component when designing for T1/E1 or ISDN-PRI applications requiring an octal transformer configuration. The 1.2mH inductance and 1:2 ratio are critical for maintaining signal fidelity in these specific protocol stacks. Consider the surface mount profile and maximum height constraints during mechanical design to ensure proper clearance within the enclosure.
Part Context
This part belongs to the family of pulse transformers from Pulse Electronics, specifically engineered for digital telephony interfaces. It serves as a key passive component in network interface units, facilitating balanced signal transmission while providing necessary galvanic isolation between the network side and the user equipment side in standard telecom architectures.
Replacement Considerations
Cross-reference with other octal pulse transformers offering identical 1.2mH inductance and 1:2 ratios. Verify that any substitute maintains the same 25.40mm x 7.87mm footprint and 7.490mm height to ensure mechanical fit without modifying the existing PCB design or assembly processes.
