GUS-QS0B-03-1912-JA Description

The GUS-QS0B-03-1912-JA from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications. This 19-resistor array features a 19.1KΩ resistance value per resistor with a 5% tolerance and a ±25ppm/°C temperature coefficient, ensuring stable performance across a 70°C to 125°C derated power range. Housed in a 20-pin QSOP package, it offers a compact 8.66mm × 6.02mm footprint with a 1.47mm profile, ideal for space-constrained surface-mount (SMD) designs. Rated for 1W total power dissipation (0.05W per resistor) and 100V maximum voltage, it combines reliability with high-density integration. The gull-wing termination ensures secure PCB mounting, while the tube packaging facilitates automated assembly.
