Overview
The TX1471NLT is an octal pulse transformer manufactured by Pulse Electronics, designed for T1/E1 and ISDN-PRI applications. It features a 1:1 turns ratio and a nominal inductance of 1.2 mH. The component utilizes a surface-mount package with dimensions of 25.40 mm length, 7.87 mm width, and a maximum height of 7.49 mm. It operates within a temperature range of -40°C to 85°C and complies with RoHS3 standards.
Feature Summary
- Octal configuration supporting eight-channel signal transmission
- Surface-mount design for automated PCB assembly
- Optimized for T1/E1 and ISDN-PRI network interfaces
Applications
- T1 digital carrier systems
- E1 telecommunications networks
- ISDN Primary Rate Interface (PRI) equipment
- CEPT standard communication devices
Procurement Notes
Verify the specific ordering suffix against official datasheets to ensure correct packaging and variant selection. Confirm that the component meets required environmental certifications such as RoHS3 for the target market. Cross-reference manufacturer part numbers with distributor listings to validate authenticity and current production status before finalizing procurement orders.
Selection Notes
Select this component when designing circuits requiring isolated signal coupling for T1 or E1 lines. Ensure the PCB layout accommodates the specified 25.40 mm x 7.87 mm footprint and 7.49 mm height clearance. Verify thermal management strategies are adequate for operation up to 85°C, as performance may degrade near upper temperature limits.
Part Context
This transformer belongs to Pulse Electronics' audio and signal transformer portfolio, specifically engineered for telecommunications infrastructure. It serves as a critical interface component for maintaining signal integrity in high-speed digital data transmission environments, replacing older through-hole variants with compact surface-mount solutions.
Replacement Considerations
The TX1471NL is documented as a parameter-equivalent substitute. Verify pin compatibility and mechanical fit before substitution.
