TX1474NLT

Overview

The TX1474NLT is a surface-mount pulse transformer manufactured by Pulse Electronics. It features an octal package configuration with a turns ratio of 1:2.42 and an inductance of 1.2 mH. The component is designed for T1/E1, CEPT, and ISDN-Primary applications. It supports multi-port connectivity, specifically an 8-port arrangement, ensuring reliable signal transmission in telecommunications environments.

Feature Summary

• Octal surface-mount construction for compact integration
• Designed for T1/E1 and ISDN-Primary network interfaces
• Supports 8-port connectivity configurations

Applications

• T1/E1 telecommunication systems
• CEPT network interfaces
• ISDN-Primary digital subscriber lines

Procurement Notes

Verify the specific pinout and port configuration against the official datasheet to ensure compatibility with the target circuit design. Confirm that the octal package dimensions align with the PCB footprint requirements. Ensure the selected variant meets the necessary isolation and impedance specifications for the intended T1/E1 application environment.

Selection Notes

Select this component when designing for T1/E1 or ISDN-Primary protocols requiring an 8-port interface. The choice depends on the need for a 1.2 mH inductance value and a 1:2.42 turns ratio within an octal SMD form factor. Consider thermal management and board space constraints associated with the octal package size during the layout phase.

Part Context

This part belongs to the family of audio and signal transformers produced by Pulse Electronics. It serves as a critical interface component in digital telephony infrastructure, facilitating signal integrity between network equipment and subscriber lines. The octal packaging distinguishes it from standard dual-inline or single-chip transformer solutions used in lower-density applications.
