GUS-QS0B-03-1872-J Description

The GUS-QS0B-03-1872-J is a high-performance thin-film resistor network from TT Electronics/IRC, designed for precision applications in compact surface-mount assemblies. This 20-pin QSOP (Quarter Small Outline Package) device integrates 19 resistors, each with a 18.7KΩ resistance value and a tight 5% tolerance, ensuring consistent performance across demanding circuits. With a ±25ppm/°C temperature coefficient, it delivers exceptional stability over the 70°C to 125°C derated power range, making it suitable for environments with fluctuating thermal conditions. The network supports a maximum voltage rating of 100V and a total power dissipation of 1W (0.05W per resistor), ideal for distributed power management. Its gull-wing termination and 0.64mm terminal pitch facilitate reliable PCB mounting in space-constrained designs.
