GUS-QS8A-03-1101-BB Description

The GUS-QS8A-03-1101-BB is a high-precision thin-film resistor network from TT Electronics/IRC, designed for demanding surface-mount (SMD) applications. This 16-pin QSOP package features eight isolated 1.1KΩ resistors with an ultra-tight tolerance of ±0.1% and a low temperature coefficient (TCR) of ±25ppm/°C, ensuring stable performance across a wide temperature range (70°C to 125°C). With a power rating of 0.75W (3/4W) total (0.1W per resistor) and a maximum voltage rating of 100V, this network is engineered for reliability in precision circuits. Its gull-wing termination and 0.64mm terminal pitch facilitate easy PCB integration, while the compact 4.9mm × 6.02mm × 1.47mm footprint optimizes space efficiency.
