TX1491T

Overview

The TX1491T is a surface-mount audio and signal transformer manufactured by Pulse Electronics. It is designed for use in telecommunications applications, specifically supporting T1, CEPT, and ISDN-Pri standards. The component features a single-port configuration with a primary inductance of 1200 uH and a DC resistance of 2.7 Ohms. It is constructed as an integrated circuit chip package suitable for automated assembly processes.

Feature Summary

Supports T1, CEPT, and ISDN-Pri signaling standards
Surface-mount design for automated PCB assembly
Single-port audio and signal transformation

Applications

T1 line interface circuits
CEPT standard telephony systems
ISDN Primary Rate Interface equipment

Procurement Notes

Verify the specific ordering suffix to ensure compatibility with required RoHS compliance and lead-free status. Confirm that the surface-mount package dimensions match the target PCB footprint. Cross-reference the manufacturer datasheet for precise electrical tolerances and thermal specifications before finalizing the bill of materials.

Selection Notes

Select this component when designing interfaces for T1, CEPT, or ISDN-Pri networks requiring surface-mount integration. Ensure the application environment supports the specified operating temperature range. Verify impedance matching requirements against the 1200 uH inductance specification to maintain signal integrity in digital telephony applications.

Part Context

This part belongs to the Pulse Transformers product line, categorized under audio and signal transformers. It serves as a critical passive component for isolating and transforming signals in digital communication hardware. The series includes variants such as TX1491 and TX1491NLT, differentiated by packaging and compliance attributes.

Replacement Considerations

The TX1491 is listed as a related variant. Verify if the non-T suffix meets the same mechanical and electrical requirements. Check for availability of TX1491NLT if lead-free certification is mandatory for the end product.
