GUS-QS8B-03-7151-B Description

The GUS-QS8B-03-7151-B from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding electronic applications. It features 15 resistors in a 16-pin QSOP package with a 7.15KΩ resistance value and an ultra-tight 0.1% tolerance, ensuring exceptional accuracy. The device operates over a wide temperature range of 70°C to 125°C with a derated power capability, making it suitable for environments with thermal fluctuations. Its ±25ppm/°C temperature coefficient minimizes resistance drift, while the 0.75W (3/4W) total power rating and 0.05W per resistor provide robust performance in compact designs. The gull-wing termination and surface-mount (SMD) configuration facilitate easy PCB integration.
