Overview
The TGR74-3755NCRLTR is a surface-mount isolation transformer module from HALO Electronics, designed for T1/E1 reinforced applications. It features a dual-channel configuration within an SMD-12 package, providing 3.75 kV insulation voltage and 1.5 mH inductance. The component operates between -40°C and +85°C with a frequency range of 100 kHz to 10 MHz.
Feature Summary
- Provides reinforced electrical isolation suitable for T1/E1 telecommunication standards
- Integrates dual channels into a compact surface-mount footprint
- Features shielded construction to minimize electromagnetic interference
Applications
- T1/E1 interface circuits
- Telecommunications line protection modules
- Digital signal isolation interfaces
Procurement Notes
Verify the specific suffix 'NCRL' against official HALO documentation to confirm lead frame material and plating specifications. Ensure the selected variant matches the required insulation class and thermal rating for the target application environment before finalizing procurement orders.
Selection Notes
Select this component when high-voltage isolation is required for single-port T1/E1 lines. Compare the 3.75 kV rating against lower-rated alternatives if system safety margins demand enhanced dielectric strength. Verify that the SMD-12 package dimensions fit the available PCB real estate constraints.
Part Context
This part belongs to the TGR series of telecom transformers from HALO Electronics. It is specifically engineered for digital transmission systems requiring robust signal integrity and galvanic isolation. The product line supports various port configurations and voltage ratings for different network protocols.
Replacement Considerations
Consult official HALO cross-reference lists for verified substitutes. Generic audio transformers may not meet the specific T1/E1 reinforcement requirements or insulation voltage ratings necessary for this application.
