GUS-QS8A-03-4022-BA Description

The GUS-QS8A-03-4022-BA from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding surface-mount applications. This 16-pin QSOP package integrates eight isolated 40.2KΩ resistors with an ultra-tight tolerance of ±0.1% and a low temperature coefficient of ±25ppm/°C, ensuring exceptional stability across a wide operating range of -70°C to +125°C. With a 0.75W (3/4W) total power rating (0.1W per resistor) and a 100V maximum voltage rating, it delivers robust performance in compact designs. The gull-wing termination and 0.64mm terminal pitch facilitate reliable PCB mounting, while its 1.47mm low-profile height (1.63mm seated) suits space-constrained layouts.
