GUS-QS8A-03-3900-DA Description

The GUS-QS8A-03-3900-DA is a high-precision 8-resistor isolated network from TT Electronics/IRC, designed for demanding surface-mount applications. Featuring a 390Ω resistance value with a tight 0.5% tolerance and a low ±25ppm/°C temperature coefficient, this thin-film resistor network ensures stable performance across a wide temperature range of 70°C to 125°C. Encased in a 16-pin QSOP package with gull-wing terminations, it offers a compact footprint (4.9mm × 6.02mm × 1.47mm) and robust 0.75W (3/4W) total power rating, making it suitable for high-density PCB designs.

GUS-QS8A-03-3900-DA Features

• Precision Thin Film Technology: Delivers superior accuracy (±0.5%) and low TCR (±25ppm/°C) for stable operation in fluctuating thermal conditions.
• Isolated Circuit Design (ISOL): Each resistor operates independently, ideal for applications requiring electrical isolation.
• High Power Handling: 0.1W per resistor (0.75W total) and 100V maximum voltage rating ensure reliability in power-sensitive circuits.
• Compact QSOP Package: Space-saving 0.64mm terminal pitch and 1.63mm seated height enable integration in miniaturized designs.
• Industrial-Grade Durability: Withstands 125°C maximum operating temperature, suited for harsh environments (non-automotive).
