Designed for telecommunications applications, it operates within a standard temperature range and complies with RoHS standards.

Feature Summary

• Four-port architecture supporting T1, E1, CEPT, and ISDN-PRI signal transmission
• Surface-mount termination style for automated assembly integration
• High isolation voltage capability ensuring circuit protection

Applications

• T1 line interface circuits
• E1 digital subscriber line systems
• ISDN primary rate interface modules

Procurement Notes

Verify the specific package variant required, as tape-and-reel packaging typically requires a 'T' suffix (e.g., TX1263NLT). Confirm that the selected component meets the necessary environmental compliance standards for your target market. Ensure the datasheet specifications align with your system's electrical requirements before finalizing procurement orders.

Selection Notes

Select this component when designing interfaces for T1, E1, or ISDN-PRI networks requiring a compact surface-mount solution. The 1:2 turns ratio and 1.2 mH inductance are critical for matching impedance in these specific telecommunication protocols. Consider the physical dimensions and mounting type to ensure compatibility with your PCB layout constraints.

Part Context

This transformer belongs to the family of audio and signal transformers used in digital telecommunications infrastructure.
