GUS-QS0B-03-1741-BA Description

The GUS-QS0B-03-1741-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 1.74 kΩ resistance value and an ultra-tight 0.1% tolerance, ensuring exceptional accuracy. The network operates over a wide temperature range of 70°C to 125°C (derated) with a ±25 ppm/°C temperature coefficient, delivering stable performance under thermal stress. Its 1W total power rating (0.05W per resistor) and 100V maximum voltage rating make it suitable for high-reliability circuits. The gull-wing termination and surface-mount design facilitate automated assembly, while the tube packaging ensures safe handling and storage.
