TG91-1505NZLF

Pulse Transformers Overview

The TG91-1505NZLF is a surface-mount T1/E1 dual pulse transformer manufactured by HALO Electronics, Inc. It features a 24-pin SMD package designed for isolation modules. The component supports a transmitter configuration of 1CT:2.4CT and a receiver configuration of 1CT:1CT. It is classified as an audio and signal transformer within the SMD-T1 series, intended for digital communication applications requiring electrical isolation.

Pulse Transformers Feature Summary

• Dual port architecture supporting simultaneous T1 and E1 signal processing
• Surface mount design for automated assembly integration
• Integrated isolation module functionality for signal integrity

Pulse Transformers Applications

• T1 transmission line interface circuits
• E1 transmission line interface circuits
• Digital subscriber line equipment
• Telecommunications network interface units

Pulse Transformers Procurement Notes

Verify the specific suffix 'NZLF' to confirm the dual-port variant with lead-free compliance. Confirm the 24-pin surface mount footprint matches the target PCB layout. Ensure the transmitter and receiver turn ratios align with the system design requirements before procurement.

Pulse Transformers Selection Notes

Select this component when a dual-channel isolation solution is required for T1 or E1 standards. Compare pin counts and physical dimensions against single-port alternatives if space is constrained. Verify that the surface mount package type suits the manufacturing process capabilities.

Pulse Transformers Part Context

This part belongs to the HALO Electronics SMD-T1 series of isolation transformers. It is distinct from single-port variants like the TG70 series and quad-port models such as the TG91-1505NURL. The device serves as a critical passive component in digital telephony interfaces.

Pulse Transformers Replacement Considerations

Direct substitutes include other HALO Electronics dual-port T1/E1 transformers such as the TG91-1505NZRL. Verify pin compatibility and electrical specifications before cross-referencing with non-HALO manufacturers.
