TG49-LVL1NXRL

Pulse Transformers Overview

The TG49-LVL1NXRL is a surface-mount isolation module from HALO Electronics, designed for T1/E1 applications. It features a Gull-Wing SMD package with 40 pins and supports QuadPort configurations. The device includes common mode chokes and provides electrical isolation. Key specifications include a primary DC resistance of 0.8 Ohms and a turns ratio configuration of 1:2CT/1CT:2. It operates within standard industrial temperature ranges and is shielded to minimize electromagnetic interference.

Pulse Transformers Feature Summary

• Supports T1/E1 signal transmission standards
• Integrates common mode chokes for noise reduction
• Utilizes a Gull-Wing SMD package for reliable mounting

Pulse Transformers Applications

• T1 network interface units
• E1 telecommunications equipment
• Digital subscriber line (DSL) modems
• Network interface cards (NICs)

Pulse Transformers Procurement Notes

Verify the specific package variant against project requirements, as HALO offers both RL (Reel) and LF (Tube) suffixes which differ in packaging but may share core electrical characteristics. Confirm that the 0.8 Ohm primary DCR aligns with the system's power budget. Ensure the Gull-Wing footprint matches the PCB layout constraints. Cross-reference the latest datasheet for any recent product change notifications or lead time updates before finalizing the bill of materials.

Pulse Transformers Selection Notes

Select this component when designing for T1/E1 interfaces requiring integrated common mode filtering and galvanic isolation in a compact surface-mount form factor. The Gull-Wing package offers mechanical stability compared to standard SMD options. Consider the 1:2CT/1CT:2 ratio for compatibility with standard transformer-coupled transceiver circuits. Evaluate thermal performance if operating near the upper temperature limits.

Pulse Transformers Part Context

This part belongs to the TG49 series of audio and signal transformers from HALO Electronics. It is categorized under LAN and telecom isolation modules. The series typically includes variants for different data rates and port configurations, such as single-port or quad-port designs. The TG49-LVL1NXRL specifically targets high-reliability telecommunications infrastructure.

Pulse Transformers Replacement Considerations

The TG49-LVL1NXLFTR is a pin-compatible alternative from the same manufacturer, differing primarily in reel versus tube packaging. Other generic equivalents may exist but require careful verification of the 1:2CT/1CT:2 ratio and 0.8 Ohm DCR to ensure functional parity in T1/E1 applications.
