GUS-QS8A-02-9090-JB Description

The GUS-QS8A-02-9090-JB from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications in surface-mount PCB assemblies. This 16-pin QSOP package features 8 isolated resistors, each with a 909Ω resistance value and a 5% tolerance, ensuring stable performance in compact designs. With a 0.75W (3/4W) total power rating and 0.1W per resistor, it operates reliably across a wide temperature range of 70°C to 125°C, derated for optimal efficiency. The ±50ppm/°C temperature coefficient guarantees minimal resistance drift, making it ideal for environments requiring thermal stability.
