GUS-QS8A-03-4322-BA Description

The GUS-QS8A-03-4322-BA is a high-precision thin-film resistor network from TT Electronics/IRC, designed for demanding surface-mount applications. This 16-pin QSOP (Quarter Small Outline Package) device integrates eight isolated 43.2KΩ resistors with an exceptional tolerance of ±0.1% and a low temperature coefficient of ±25ppm/°C, ensuring stable performance 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 combines reliability with compactness (4.9mm × 6.02mm × 1.47mm), making it ideal for space-constrained designs. The gull-wing termination and 0.64mm terminal pitch facilitate robust PCB assembly.
