GUS-QS8A-00-27R0-GF Description

The GUS-QS8A-00-27R0-GF is a high-performance 8-resistor thin film network from TT Electronics/IRC, designed for precision applications requiring stable resistance and compact packaging. Encased in a 16-pin QSOP (Quarter Small Outline Package) with gull-wing SMD termination, this 27 Ohm, 2% tolerance network offers a ±250ppm/°C temperature coefficient, ensuring reliable performance across a wide temperature range (70°C to 125°C). Its isolated (ISOL) circuit design provides individual resistor functionality, while the 0.75W (3/4W) total power rating (0.1W per resistor) and 100V maximum voltage rating make it suitable for demanding circuits. The thin film technology ensures low noise and high accuracy, ideal for signal conditioning and analog systems.

GUS-QS8A-00-27R0-GF Features

• Compact & Robust: 4.9mm x 6.02mm x 1.47mm QSOP package with ±0.1mm length/height tolerances for high-density PCB layouts.
• Precision Performance: 2% tolerance and ±250ppm/°C TCR for stable operation in varying environments.
• High Power Handling: 0.75W total power dissipation (0.1W per resistor) at 125°C maximum operating temperature.
• Isolated Design: 8 independent resistors (ISOL configuration) for flexible circuit integration.
• Surface-Mount Ready: Gull-wing terminals with 0.64mm pitch for automated assembly compatibility.
• Non-Automotive: Compliant with EAR99 ECCN but not PPAP or automotive-grade.
