GUS-QS0B-03-1802-FA Description

The GUS-QS0B-03-1802-FA from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding surface-mount applications. This 20-pin QSOP (Quarter Small Outline Package) device integrates 19 resistors, each with an 18K Ohm resistance, a tight 1% tolerance, and a low ±25ppm/°C temperature coefficient, ensuring stable performance across a -70°C to +125°C operating range. With a 1W total power rating (0.05W per resistor) and a 100V maximum voltage rating, it delivers reliable signal conditioning, voltage division, and pull-up/down functions in compact PCB layouts. The gull-wing termination and 0.64mm terminal pitch facilitate automated assembly, while the 1.47mm low-profile height suits space-constrained designs. Packaged in a tube for handling efficiency, this non-automotive, non-PPAP compliant network is ideal for industrial and telecom systems requiring precision and durability.
