GUS-QS8B-03-9102-J Description

The GUS-QS8B-03-9102-J from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications in demanding electronic circuits. This 16-pin QSOP (Quarter-Small Outline Package) device integrates 15 resistors, each with a 91kΩ resistance value and a tight ±5% tolerance, ensuring reliable performance in signal conditioning, voltage division, and impedance matching. With a power rating of 0.75W (3/4W) total and 0.05W (1/20W) per resistor, it supports moderate power dissipation while maintaining stability across a wide temperature range of -70°C to +125°C. The ±25ppm/°C temperature coefficient minimizes resistance drift, making it ideal for environments with fluctuating thermal conditions.
