GUS-QS8B-03-1822-JG Description

The GUS-QS8B-03-1822-JG from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications in surface-mount assemblies. This 16-pin QSOP package integrates 15 resistors, each with a 18.2KΩ resistance value and a tight ±5% tolerance, ensuring consistent performance in demanding circuits. With a 0.75W (3/4W) total power rating and 0.05W (1/20W) per resistor, it balances power handling with compactness. The device operates across a wide temperature range (70°C to 125°C derated, 125°C max), supported by a low ±25ppm/°C temperature coefficient, making it stable under thermal stress. Its gull-wing termination and 0.64mm terminal pitch facilitate reliable PCB mounting.
