GUS-QS0B-03-4642-JC Description

The GUS-QS0B-03-4642-JC from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications. This 20-pin QSOP surface-mount device integrates 19 resistors, each with a 46.4KΩ resistance value and a 5% tolerance, ensuring reliable signal conditioning and voltage division. With a ±25ppm/°C temperature coefficient, it delivers exceptional stability across a 70°C to 125°C derated power range, making it suitable for environments with fluctuating thermal conditions. The 1W total power rating (0.05W per resistor) and 100V maximum voltage rating further enhance its robustness in demanding circuits. Packaged in a tube for automated assembly, this gull-wing-terminated network combines compact dimensions (8.66mm x 6.02mm x 1.47mm) with high-density integration.

GUS-QS0B-03-4642-JC Features
