GUS-QS8A-03-6490-GG Description

The GUS-QS8A-03-6490-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 isolated network features a 649Ω 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 (Quarter Small Outline Package) with gull-wing SMD terminations, it offers a compact footprint (4.9mm x 6.02mm x 1.47mm) ideal for space-constrained PCB designs. The 0.1W (1/10W) power rating per resistor and 0.75W (3/4W) total power dissipation make it suitable for moderate-power applications, while its 100V maximum voltage rating ensures robustness in demanding circuits.
