GUS-QS8B-02-5491-GF Description

The GUS-QS8B-02-5491-GF from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications in surface-mount configurations. This 16-pin QSOP package features 15 resistors with a 5.49KΩ resistance value, offering a tight 2% tolerance and a low ±50ppm/°C temperature coefficient, ensuring stability across a wide operating temperature range of 70°C to 125°C. With a 0.75W (3/4W) total power rating and 0.05W (1/20W) per resistor, it balances compactness with robust performance. The gull-wing termination and 100V maximum voltage rating make it suitable for high-density PCB designs requiring reliable signal conditioning or voltage division.
