GUS-QS8A-03-71R5-GD Description

The GUS-QS8A-03-71R5-GD from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications. This 16-pin QSOP package features 8 isolated resistors, each with a 71.5Ω resistance value and a tight 2% tolerance, ensuring consistent performance in demanding circuits. With a power rating of 0.75W (3/4W) total and 0.1W (1/10W) per resistor, it operates reliably across a temperature range of 70°C to 125°C, derated for optimal thermal management. The ±25ppm/°C temperature coefficient enhances stability in environments with fluctuating temperatures. Its gull-wing termination and 0.64mm terminal pitch facilitate easy surface-mount (SMD) integration, while the compact 4.9mm x 6.02mm x 1.47mm footprint saves board space.
