GUS-QS8A-01-2552-GB Description

The GUS-QS8A-01-2552-GB from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications in surface-mount PCB assemblies. This 16-pin QSOP package integrates 8 isolated resistors, each with a 25.5KΩ resistance value and a tight 2% tolerance, ensuring consistent performance in demanding circuits. The network operates over a wide temperature range of 70°C to 125°C (derated) and can withstand 125°C maximum operating temperature, making it suitable for environments with thermal stress. With a ±100ppm/°C temperature coefficient, it delivers excellent stability under varying thermal conditions. The 0.75W (3/4W) total power rating and 0.1W (1/10W) per resistor provide robust power handling in compact designs.
