GUS-QS0B-03-9090-FC Description

The GUS-QS0B-03-9090-FC 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 with a 909Ω resistance value, offering 1% tolerance and a low ±25ppm/°C temperature coefficient. Rated for 1W total power dissipation (0.05W per resistor), it operates reliably across a wide temperature range of 70°C to 125°C, with a maximum operating temperature of 125°C. Its gull-wing termination and 0.64mm terminal pitch ensure compatibility with automated PCB assembly processes. The compact dimensions (8.66mm x 6.02mm x 1.47mm) make it ideal for space-constrained designs.
