GUS-QS8B-01-7872-J Description

The GUS-QS8B-01-7872-J from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications in surface-mount configurations. This 16-pin QSOP package integrates 15 resistors, each with a 78.7K Ohm resistance value and a tight 5% tolerance, ensuring reliable performance in demanding circuits. The network operates over a wide temperature range of 70°C to 125°C (derated) with a maximum operating temperature of 125°C, making it suitable for environments requiring thermal stability. Its thin-film technology delivers a low ±100ppm/°C temperature coefficient, minimizing resistance drift under varying conditions. The 0.75W (3/4W) total power rating and 100V maximum voltage rating further enhance its robustness in power-sensitive designs.
