GUS-QS0B-02-5621-B Description

The GUS-QS0B-02-5621-B from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding electronic applications. It features 19 resistors in a 20-pin QSOP package, each with a 5.62KΩ resistance and an ultra-tight 0.1% tolerance, ensuring exceptional accuracy. The device operates over a wide temperature range (-70°C to +125°C) with a ±50ppm/°C temperature coefficient, making it suitable for environments with thermal fluctuations. Its 1W total power rating (0.05W per resistor) and 100V maximum voltage rating provide robust performance in compact designs. The gull-wing termination and surface-mount (SMD) configuration facilitate easy PCB integration.
