GUS-QS8A-03-9312-GG Description

The GUS-QS8A-03-9312-GG is a high-performance thin-film resistor network from TT Electronics/IRC, designed for precision applications requiring stable resistance values and low temperature coefficients. This 8-resistor network features a 93.1K Ohm resistance per element with a tight 2% tolerance and an ultra-low ±25ppm/°C temperature coefficient, ensuring reliable performance across a wide operating temperature range of 70°C to 125°C. Packaged in a 16-pin QSOP with gull-wing SMD termination, it offers excellent space efficiency for densely populated PCBs. The isolated (ISOL) circuit design allows for flexible routing, while the 0.75W (3/4W) total power rating (0.1W per resistor) ensures durability in demanding environments.
