GUS-QS0B-03-4872-BA Description

The GUS-QS0B-03-4872-BA from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding electronic applications. This 20-pin QSOP (Quarter Small Outline Package) device integrates 19 resistors, each with a 48.7KΩ resistance, offering a tight 0.1% tolerance and a low ±25ppm/°C temperature coefficient. With a 1W total power rating (0.05W per resistor) and a maximum operating temperature of 125°C, it ensures stable performance in thermally challenging environments. The gull-wing termination and 0.64mm terminal pitch facilitate reliable surface-mount assembly, while its compact dimensions (8.66mm × 6.02mm × 1.47mm) make it ideal for space-constrained PCB designs.
