GUS-QS8A-03-5491-JB Description

The GUS-QS8A-03-5491-JB is a high-performance thin-film resistor network from TT Electronics/IRC, designed for precision applications in surface-mount configurations. This 16-pin QSOP package features 8 isolated resistors, each with a 5.49KΩ resistance and a 5% tolerance, ensuring reliable signal conditioning and voltage division. With a ±25ppm/°C temperature coefficient, it delivers exceptional stability across a wide operating range of -70°C to +125°C. The 0.75W (3/4W) total power rating (0.1W per resistor) and 100V maximum voltage rating make it suitable for demanding environments. Its gull-wing termination ensures secure PCB mounting, while the compact 4.9mm × 6.02mm × 1.47mm footprint optimizes space efficiency.
