TX1341NL

Overview

The TX1341NL is a surface-mount pulse transformer manufactured by Pulse Electronics, designed for T1/E1 and ISDN-PRI applications. It features an octal configuration with eight ports, providing a primary-to-secondary turns ratio of 1:2. The component exhibits a nominal inductance of 1.2mH and operates within a temperature range of -40°C to 85°C. Its physical dimensions are 25.40mm in length, 7.87mm in width, and a maximum height of 7.49mm. The device is moisture sensitive (MSL level 3) and complies with RoHS3 standards.

Feature Summary

• Octal design supporting eight independent signal paths for multi-channel transmission
• Optimized magnetic performance for T1/E1 and ISDN-PRI line interface requirements
• Surface mount construction suitable for automated PCB assembly processes

Applications

• T1 digital carrier systems
• E1 digital carrier networks
• ISDN Primary Rate Interface (PRI) equipment
• CEPT standard telecommunications interfaces

Procurement Notes

Verify the specific suffix designation when ordering, as variants such as TX1341NLT may differ in packaging format while retaining identical electrical characteristics. Confirm that the required quantity aligns with the manufacturer's standard package size of 200 units per tube. Ensure storage conditions adhere to the specified Moisture Sensitivity Level 3 guidelines to prevent internal damage during reflow soldering. Cross-reference the datasheet version to confirm compatibility with current production revisions.

Selection Notes

Select this component for designs requiring isolated signal coupling in high-speed digital telephony circuits. The 1.2mH inductance value ensures adequate low-frequency response for standard T1/E1 signaling rates. The 1:2 turns ratio matches typical impedance transformation needs for these protocols. Consider the 25.40mm footprint when planning board layout constraints. Verify thermal management capabilities given the 85°C maximum operating temperature limit.

Part Context

This part belongs to the TX1xxxNL series of telecommunications transformers from Pulse Electronics. These components are engineered specifically for network interface units and digital subscriber line access multiplexers. The series provides reliable isolation between line-side and circuit-side electronics. The TX1341NL represents a specialized variant optimized for octal port configurations common in legacy and hybrid telecom infrastructure.

Replacement Considerations

Publicly confirmed substitute part numbers include TX1341-44NL and TX1470-75NL. These alternatives share similar application domains but may exhibit differences in specific electrical parameters or pinout configurations. Verify functional equivalence against the original design specifications before implementation.
