GUS-QS0B-03-1801-JB Description

The GUS-QS0B-03-1801-JB from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications in surface-mount PCB assemblies. This 20-pin QSOP (Quarter Small Outline Package) device integrates 19 resistors, each with a 1.8KΩ resistance value and a 5% tolerance, delivering a total power rating of 1W (0.05W per resistor). Engineered with thin-film technology, it offers superior stability with a low temperature coefficient of ±25ppm/°C, ensuring reliable performance across a wide temperature range of 70°C to 125°C. The gull-wing termination facilitates robust soldering, while the compact 8.66mm × 6.02mm × 1.47mm footprint optimizes board space.
