GUS-QS8A-02-1781-CB Description

The GUS-QS8A-02-1781-CB from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding surface-mount applications. This 16-pin QSOP (Quarter-Small Outline Package) device integrates eight isolated 1.78KΩ resistors with an exceptional tolerance of ±0.25% and a low ±50ppm/°C temperature coefficient, ensuring stable performance across a wide operating temperature 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 compact dimensions (4.9mm x 6.02mm x 1.47mm). The gull-wing termination facilitates robust PCB mounting, while the tube packaging ensures safe handling and storage.
