Overview
The TX1193NLT is a T1/E1 dual pulse transformer from Pulse Electronics, designed for surface mount applications. It features a primary-to-secondary turns ratio of 1CT:2CT for the transmitter and 1CT:1CT for the receiver. The module provides an inductance of 1.2mH and operates within a temperature range of -40°C to +85°C. The component measures 17.53mm in length, 12.20mm in width, and has a maximum seated height of 5.76mm. It complies with RoHS3 standards and carries a Moisture Sensitivity Level (MSL) rating of 4.
Feature Summary
- Provides electrical circuit isolation compliant with IEEE 802.3 standards for signal integrity
- Optimized specifically for T1/E1 dual channel telecommunications transceivers
- Supports peak reflow temperatures up to +245°C for standard SMT assembly processes
Applications
- T1/E1 line interface circuits
- Telecommunications network equipment
- Digital subscriber line (DSL) systems
Procurement Notes
Verify that the specific order matches the 'NLT' suffix designation, which indicates tape and reel packaging, distinct from the 'NL' variant. Confirm the manufacturer part number against official datasheets to ensure correct polarity and pinout configuration for the intended PCB layout. Check for recent Product Change Notifications regarding alternative locations or material updates.
Selection Notes
Select this component when designing for T1/E1 dual-channel architectures requiring specific 1CT:2CT and 1CT:1CT impedance matching. Ensure the operating environment stays within the specified -40°C to +85°C range. Consider the MSL 4 rating for appropriate moisture management during storage and soldering. Verify footprint compatibility with the 17.53mm x 12.20mm dimensions.
Part Context
This part belongs to the Pulse Electronics LAN discrete transformer modules family, optimized for major LAN transceivers. While similar modules in the series support frequencies from 1kHz to 100MHz, the TX1193NLT is specifically tuned for T1/E1 telecom standards. It shares design characteristics with other surface mount pulse transformers but is distinct in its dual-channel configuration and specific inductance values.
Replacement Considerations
The TX1193NLT is listed as a parameter-equivalent substitute for the TX1193NL. Both parts share identical electrical specifications and form factor, differing primarily in packaging format.
