TX1295NLT

Overview

The TX1295NLT is a surface mount audio and signal transformer manufactured by Pulse Electronics. Designed for T1/E1 Quad applications, this component features a transmitter configuration with a 1:1.26CT turns ratio and a receiver configuration with a 1:1.26CT turns ratio. The unit operates within a standard industrial temperature range and utilizes an SMD/SMT mounting style for automated assembly. It is classified under Audio & Signal Transformers and serves as a critical interface element in telecommunications signaling circuits.

Feature Summary

Supports T1/E1 Quad transmission standards
Integrated transmitter and receiver isolation
Surface mount package for PCB integration

Applications

T1 line driver circuits
E1 network interface units
Telecommunications signal conditioning

Procurement Notes

Verify the specific datasheet revision to confirm mechanical dimensions and electrical tolerances against the design requirements. Ensure the supplier provides traceability documentation compliant with industry standards. Confirm that the component meets all necessary environmental certifications required for the target deployment region before finalizing the purchase order.

Selection Notes

Select this transformer when designing systems requiring standardized T1 or E1 quad interface isolation. The 1:1.26CT ratio is specific to these legacy telephony protocols. Evaluate board space constraints due to the surface mount form factor. Consider thermal management capabilities if the operating environment exceeds standard commercial limits.

Part Context

This component belongs to Pulse Electronics' portfolio of audio and signal transformers. It is distinct from power inductors and common mode chokes found in other product lines. The TX series focuses on high-frequency signal integrity for digital telephony applications rather than power conversion or noise filtering in DC-DC converters.
