GUS-QS0B-03-1182-CC Description

The GUS-QS0B-03-1182-CC from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding surface-mount applications. This 20-pin QSOP package integrates 19 resistors, each with a tight tolerance of ±0.25% and a low temperature coefficient of ±25ppm/°C, ensuring stable performance across a wide temperature range of 70°C to 125°C. With a resistance value of 11.8KΩ per resistor and a derated power rating of 0.05W (1/20W) per element, this network delivers 1W total power dissipation, making it suitable for precision analog and digital circuits. Its gull-wing termination and 0.64mm terminal pitch facilitate reliable PCB mounting, while the compact 8.66mm × 6.02mm × 1.47mm footprint optimizes board space.
