GUS-QS8A-02-6340-JA Description

The GUS-QS8A-02-6340-JA from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications in surface-mount configurations. This 16-pin QSOP (Quarter Small Outline Package) device features 8 isolated resistors, each with a 634Ω resistance value, 5% tolerance, and a ±50ppm/°C temperature coefficient. With a 0.75W (3/4W) total power rating and 0.1W (1/10W) per resistor, it operates reliably across a wide temperature range of -70°C to +125°C, making it suitable for demanding environments. The gull-wing termination ensures secure PCB mounting, while the compact 4.9mm × 6.02mm × 1.47mm footprint optimizes space efficiency.
