Overview
The TX1188NLT is a surface-mount pulse transformer manufactured by Pulse Electronics, designed for T1/E1 and ISDN-Primary Rate Interface (PRI) applications. It features dual-channel construction with an inductance of 1200µH per channel and a primary-to-secondary turns ratio of 1CT:1CT. The component operates within a temperature range of -40°C to 85°C and has a maximum installed height of 6.22mm. Its physical dimensions are 12.83mm in length and 7.11mm in width. The device is RoHS3 compliant and classified under HTSUS code 8504.31.2000.
Feature Summary
- Dual-channel design supporting T1/E1 and ISDN-PRI signaling standards
- Surface-mount package optimized for automated assembly processes
- High isolation capability suitable for telecommunications network interfaces
Applications
- T1/E1 digital subscriber line equipment
- ISDN Primary Rate Interface terminal adapters
- Telecommunications network interface units
Procurement Notes
Verify the specific suffix 'NLT' against official datasheets to confirm tape-and-reel packaging requirements. Ensure that the 1200µH inductance specification aligns with the target circuit's impedance matching needs. Confirm compliance with RoHS3 directives if environmental regulations apply to the final assembly. Cross-reference the MSL rating with the facility's soldering profile capabilities.
Selection Notes
Select this component when designing circuits requiring robust signal integrity for T1 or E1 transmission lines. The dual-channel architecture simplifies board layout compared to discrete solutions. Consider the 6.22mm height constraint during mechanical enclosure design. Verify that the operating temperature range covers the intended deployment environment without derating issues.
Part Context
This part belongs to Pulse Electronics' portfolio of magnetics components for data communication. It serves as a critical isolation element in high-speed serial data paths. The product is distinct from LAN transformers due to its specific inductance and application focus on telecom standards rather than Ethernet protocols.
Replacement Considerations
The TX1188NL is a documented parameter-equivalent alternative available from the same manufacturer. Verify pin compatibility and mounting dimensions before substitution.
