GUS-QS8A-03-3302-GB Description

The GUS-QS8A-03-3302-GB from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications requiring stable resistance values and low thermal drift. This 16-pin QSOP surface-mount device features eight isolated 33KΩ resistors with a tight 2% tolerance and an ultra-low ±25ppm/°C temperature coefficient, ensuring reliable performance across a wide operating temperature range of -55°C to +125°C. With a 0.75W (3/4W) total power rating (0.1W per resistor) and a 100V maximum voltage rating, it is engineered for demanding circuits where accuracy and durability are critical. The gull-wing termination and 0.64mm terminal pitch facilitate easy PCB integration, while its compact 4.9mm × 6.02mm × 1.47mm footprint saves board space. Packaged in a tube for automated assembly, this RoHS-non-compliant network is ideal for industrial and instrumentation use.
