Overview
The TGR74-3755NCRL is a dual-channel isolation transformer module designed for T1/E1 reinforced applications. It features SMD/SMT termination in an SMD-24 package with dimensions of 17.78 mm length and 12.19 mm width. The component operates within a frequency range of 100 kHz to 10 MHz and provides an insulation voltage of 1.5 kV. Key electrical specifications include an inductance of 500 nH and a maximum DC resistance of 0.9 Ohms. It supports a dual channel configuration and functions reliably between -40°C and +85°C.
Feature Summary
- Provides reinforced isolation for T1/E1 digital signal transmission
- Dual-port module architecture supporting simultaneous line interfaces
- Surface-mount design optimized for automated PCB assembly processes
Applications
- T1/E1 interface circuits
- Telecommunications equipment requiring signal isolation
- Digital subscriber line (DSL) access multiplexers
Procurement Notes
Verify the specific suffix NCRL against current HALO Electronics datasheets to confirm pinout and packaging details, as manufacturing updates may occur. Confirm RoHS compliance status directly with the manufacturer or authorized distributors prior to integration. Ensure the procurement source is an authorized partner to guarantee component authenticity and traceability for critical telecom infrastructure.
Selection Notes
Select this component when designing systems requiring reinforced isolation for T1/E1 signals. Compare inductance values and physical footprint against existing designs to ensure compatibility. Verify that the 1.5 kV insulation rating meets the safety requirements of the target application environment. Consider the operating temperature range limits during thermal analysis of the final assembly.
Part Context
This part belongs to the HALO Electronics audio and signal transformer portfolio, specifically tailored for telecommunications standards. It serves as a critical interface component for isolating digital lines from network equipment. The product line emphasizes reliability in harsh industrial and telecom environments, adhering to strict international signaling protocols.
Replacement Considerations
Consult official HALO Electronics documentation for qualified substitute part numbers. Cross-reference pin configurations and electrical parameters carefully before substituting. Generic equivalents may not meet the specific reinforced isolation requirements of T1/E1 applications.
