Overview
The TGMR-Q420V8LFTR is a pulse transformer isolation module manufactured by HALO Electronics, Inc. It features a surface-mount gull-wing package with six pins. The device provides reinforced insulation rated at 4.5 kVrms. Key electrical specifications include a turns ratio of 1:0.375 and a voltage-time product (Et) of 18 V/us. This component is designed for high-reliability applications requiring galvanic isolation in compact form factors.
Feature Summary
- Provides reinforced electrical isolation between primary and secondary circuits
- Utilizes a surface-mount gull-wing package for automated PCB assembly
- Engineered for high voltage-time product performance in pulse applications
Applications
- DC-DC converter isolated gate drive circuits
- High-voltage signal transmission interfaces
- Industrial control system isolation barriers
Procurement Notes
Verify the specific suffix LFTR against official HALO Electronics documentation to confirm lead time and packaging details. Ensure the 4.5 kVrms insulation rating meets your safety standards. Cross-reference the 6-pin gull-wing footprint with your PCB design library before ordering.
Selection Notes
Select this component when a 1:0.375 turns ratio and 18 V/us Et capability are required. The 4.5 kVrms isolation level distinguishes it from lower-rated variants. Confirm that the SMD gull-wing package fits within your board space constraints compared to through-hole alternatives.
Part Context
This part belongs to the TGMR series of isolation modules from HALO Electronics. These components are specialized for pulse transformer applications where high voltage isolation and compact surface-mount integration are critical. The series supports various turns ratios and insulation levels tailored for power electronics.
Replacement Considerations
Check HALO Electronics datasheets for direct pin-compatible substitutes within the TGMR series. Verify that any alternative maintains the 4.5 kVrms insulation rating and 18 V/us Et specification.
