Overview
The TG91-S024NXLFTR is an audio isolation transformer from HALO Electronics, designed for surface-mount applications. It features a quad configuration with a primary-to-secondary turns ratio of 1:2.4 and an additional 1:1 winding. The component supports extended temperature operation (X-TEMP) ranging from -40°C to +85°C. Key electrical specifications include an inductance of 1.5 mH and an isolation voltage rating of 1.5 kV. It is supplied in tape and reel packaging.
Feature Summary
- Provides galvanic isolation between signal circuits using magnetic coupling
- Supports extended temperature range operation suitable for harsh environments
- Features a compact surface-mount design for automated assembly
Applications
- Audio signal transmission in professional equipment
- Balanced line interfacing in consumer electronics
- Isolation modules for industrial control systems
Procurement Notes
Verify the specific suffix 'N' and 'LFTR' against the manufacturer's current datasheet to confirm lead-free status and tape-and-reel packaging details. Ensure the X-TEMP designation aligns with the required thermal operating range for the target application environment before finalizing procurement.
Selection Notes
Select this component when high-voltage isolation is required alongside balanced audio signal integrity. The 1:2.4 ratio suits specific impedance matching needs, while the 1:1 option offers flexibility. Confirm that the surface-mount footprint and inductance values meet the circuit design constraints compared to through-hole alternatives.
Part Context
This part belongs to the TG91 series of audio transformers manufactured by HALO Electronics. The series focuses on providing reliable isolation for audio and signal paths in compact form factors. The specific model integrates multiple winding configurations to address complex interface requirements within a single package.
Replacement Considerations
Direct substitutes may include other HALO Electronics models within the TG91 family or similar SMD audio transformers from manufacturers like Pulse Electronics or Belden, provided they match the 1.5 kV isolation, 1.5 mH inductance, and physical footprint.
