GUS-QS0B-03-1472-J Description

The GUS-QS0B-03-1472-J from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications in surface-mount PCB assemblies. This 19-resistor array features a 14.7KΩ resistance value per resistor with a 5% tolerance and a ±25ppm/°C temperature coefficient, ensuring stable performance across a wide temperature range of 70°C to 125°C. Housed in a 20-pin QSOP package with gull-wing terminations, it offers a compact footprint (8.66mm × 6.02mm × 1.47mm) and a 0.64mm terminal pitch, making it ideal for space-constrained designs. The network supports a 1W total power rating (0.05W per resistor) and operates at a maximum voltage of 100V, with a derated power range up to 125°C. Packaged in tubes, it is suited for automated assembly processes.
