GUS-QS8A-03-3091-FB Description

The GUS-QS8A-03-3091-FB is a high-precision 8-resistor thin film network from TT Electronics/IRC, designed for demanding surface-mount applications. It features a 3.09KΩ resistance value per resistor with a tight 1% tolerance and a low ±25ppm/°C temperature coefficient, ensuring stable performance across a wide operating temperature range of -70°C to +125°C. Housed in a compact 16-pin QSOP package, this isolated network offers a 0.75W (3/4W) total power rating (0.1W per resistor) and supports a maximum voltage rating of 100V. Its gull-wing termination and 0.64mm terminal pitch facilitate reliable PCB mounting in space-constrained designs.

GUS-QS8A-03-3091-FB Features

• Thin Film Technology: Delivers superior accuracy, low noise, and long-term stability compared to thick-film alternatives.
• High Power Density: 0.75W total rating in a miniature 4.9mm × 6.02mm × 1.47mm footprint, ideal for high-density layouts.
