GUS-QS8B-03-7872-JF Description

The GUS-QS8B-03-7872-JF from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications in surface-mount assemblies. This 16-pin QSOP package integrates 15 resistors, each with a 78.7KΩ resistance value and a tight ±5% tolerance, ensuring consistent performance in demanding circuits. With a ±25ppm/°C temperature coefficient, it delivers exceptional stability across a wide operating temperature range of 70°C to 125°C, making it suitable for environments with thermal fluctuations. The 0.75W (3/4W) total power rating (0.05W per resistor) and 100V maximum voltage rating provide robust electrical performance, while the gull-wing termination ensures reliable solderability in automated PCB assembly processes.
