TX1473NLT

Overview

The TX1473NLT is a surface-mount pulse transformer manufactured by Pulse Electronics, designed for T1/CEPT and ISDN-Pri applications. It features an octal configuration with a 1:2 and 1:1 winding ratio. The component has an inductance of 1200uH and supports 8-port connectivity. It is RoHS compliant and suitable for signal transformation in telecommunications environments requiring compact SMD packaging.

Feature Summary

• Supports T1/CEPT and ISDN-Pri signal standards
• Octal package design with 1:2 and 1:1 ratios
• Surface mount technology for automated assembly

Applications

• T1 line interface circuits
• CEPT standard communication systems
• ISDN Primary Rate Interface (PRI) equipment

Procurement Notes

Verify the specific datasheet version to confirm pinout compatibility and insulation ratings. Ensure the supplier provides original manufacturer documentation to validate authenticity. Check for any recent obsolescence notices or lifecycle status updates from Pulse Electronics before finalizing procurement plans.

Selection Notes

Select this component when designing for T1 or ISDN-Pri protocols requiring an octal footprint. The 1200uH inductance and specific winding ratios are critical for impedance matching in these telecommunication interfaces. Consider the SMD form factor for space-constrained PCB layouts.

Part Context

This part belongs to the audio and signal transformer category within Pulse Electronics' portfolio. It is specifically engineered for digital telephony applications, distinguishing it from general-purpose power transformers. The octal package allows for high-density mounting on printed circuit boards used in network infrastructure.

Replacement Considerations

Consult official distributor databases for cross-reference data. Verify that any substitute maintains the exact 1:2/1:1 ratio and 1200uH inductance. Ensure physical dimensions and pin configurations match to avoid rework.
