GUS-QS0B-03-1101-DC Description

The GUS-QS0B-03-1101-DC from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding surface-mount applications. This 20-pin QSOP package integrates 19 resistors, each with a 1.1KΩ resistance and a tight 0.5% tolerance, ensuring exceptional accuracy in circuit designs. With a ±25ppm/°C temperature coefficient, it delivers stable performance across a wide temperature range (70°C to 125°C derated, 125°C max). The network supports a 1W total power rating (0.05W per resistor) and operates at up to 100V, making it suitable for high-reliability environments. Its gull-wing termination and 0.64mm pitch enable compact PCB layouts, while the 1.47mm profile ensures compatibility with space-constrained designs.

GUS-QS0B-03-1101-DC Features
