GUS-QS8A-03-9092-FA Description

The GUS-QS8A-03-9092-FA from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications. This 16-pin QSOP (Quarter-Small Outline Package) device features 8 isolated resistors, each with a 90.9 kΩ resistance value and a tight 1% tolerance, ensuring reliable signal conditioning and voltage division. With a ±25 ppm/°C temperature coefficient, it delivers exceptional stability across a wide operating range of -70°C to +125°C. The 0.75W (3/4W) total power rating (0.1W per resistor) and 100V maximum voltage rating make it suitable for demanding environments. Its gull-wing termination and surface-mount design facilitate automated PCB assembly, while the tube packaging ensures safe handling and storage.

GUS-QS8A-03-9092-FA Features

• Precision Thin Film Technology: Delivers low noise and high stability for sensitive circuits.
• Isolated Resistor Configuration (ISOL): Each of the 8 resistors operates independently, ideal for multi-channel isolation.
• Compact QSOP-16 Package: Measures just 4.9mm (L) × 6.02mm (D) × 1.47mm (H) with tight tolerances (±0.1mm length/height, ±0.2mm depth).
• High Power Handling: 0.75W total dissipation (0.1W per resistor) at 125°C derated power.
• Wide Temperature Range: Operates reliably from -70°C to +125°C, suited for industrial and automotive-adjacent applications.
• Gull-Wing SMD Termination: Ensures robust solder joints and compatibility with reflow processes.
