GUS-QS0B-03-3091-DB Description

The GUS-QS0B-03-3091-DB is a high-precision thin-film resistor network from TT Electronics/IRC, designed for demanding surface-mount (SMD) applications. It features 19 resistors in a 20-pin QSOP (Quarter Small Outline Package) with a compact 8.66mm × 6.02mm × 1.47mm footprint, making it ideal for space-constrained PCB designs. Each resistor offers a 3.09KΩ value with an ultra-tight ±0.5% tolerance and a low ±25ppm/°C temperature coefficient, ensuring stability across a wide -70°C to +125°C operating range. The network supports a 100V maximum voltage rating and delivers 0.05W (1/20W) per resistor or 1W total power dissipation, making it suitable for precision analog and digital circuits.
