GUS-QS8A-03-4990-GG Description

The GUS-QS8A-03-4990-GG from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications. This 16-pin QSOP surface-mount device features 8 isolated resistors, each with a 499Ω resistance, 2% tolerance, and a ±25ppm/°C temperature coefficient. 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. The gull-wing termination ensures secure PCB mounting, while the compact 4.9mm x 6.02mm x 1.47mm footprint makes it ideal for space-constrained designs.
