GUS-QS8A-03-6492-DB Description

The GUS-QS8A-03-6492-DB 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 8 isolated resistors, each with a 64.9KΩ resistance value and an ultra-tight ±0.5% tolerance. It operates over a wide temperature range of -70°C to +125°C, ensuring stability in harsh environments. With a ±25ppm/°C temperature coefficient, it delivers exceptional thermal performance, minimizing drift in precision circuits. The 0.75W (3/4W) total power rating (0.1W per resistor) and 100V maximum voltage rating make it suitable for power-sensitive designs. Packaged in a tube, it offers mechanical protection during handling and assembly.
