TX1472NL

Overview

The TX1472NL is a surface-mount signal transformer manufactured by Pulse Electronics, designed for T1/E1 and ISDN-PRI applications. It features an 8-port configuration with a 1:2.4 turns ratio. The component operates within a frequency range of 100 kHz to 100 MHz and provides 1500 Vrms isolation voltage. It utilizes SMD termination and has a maximum operating temperature of 85°C. The unit measures 25.4 mm in length, 12.83 mm in width, and 6.22 mm in height.

Feature Summary

• Supports T1, E1, CEPT, and ISDN-PRI signaling standards
• Provides galvanic isolation between network lines
• Designed for high-density surface-mount assembly

Applications

• T1/E1 digital subscriber line interfaces
• ISDN primary rate interface systems
• Telecommunications network equipment

Procurement Notes

Verify the specific datasheet version and RoHS compliance status prior to ordering, as manufacturing specifications may evolve. Confirm that the 8-port configuration aligns with the target circuit design requirements. Ensure storage conditions account for moisture sensitivity levels indicated in the official documentation to prevent package damage during soldering processes.

Selection Notes

Select this component when designing circuits requiring standardized T1 or E1 connectivity with space constraints favoring surface-mount technology. The 1:2.4 impedance transformation ratio must match the source and load impedances of the application. Consider the 8-port density if multiple isolated channels are needed within a single footprint compared to discrete solutions.

Part Context

This part belongs to the family of audio and signal transformers produced by Pulse Electronics. It serves as a critical interface component in telecommunications hardware, facilitating signal integrity and electrical safety. The device replaces older through-hole designs in modern compact networking gear, supporting standard digital telephony protocols.

Replacement Considerations

Consult official manufacturer substitution lists for verified equivalents. Generic cross-references may not guarantee identical magnetic characteristics or port configurations.
