GUS-SS8B-02-4992-FF Description

The GUS-SS8B-02-4992-FF from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding surface-mount applications. This 16-pin SOIC device integrates 15 resistors, each with a 49.9KΩ resistance value, 1% tolerance, and a ±50ppm/°C temperature coefficient, ensuring stable performance across a wide temperature range of 70°C to 125°C. With a 0.8W total power rating (0.05W per resistor) and a 100V maximum voltage rating, it offers reliable operation in compact, high-density circuits. The gull-wing termination and 1.27mm terminal pitch facilitate easy PCB assembly, while its 9.91mm × 5.99mm × 1.45mm footprint balances space efficiency with thermal dissipation.
