GUS-QS0B-03-3322-D Description

The GUS-QS0B-03-3322-D is a high-precision thin-film resistor network from TT Electronics/IRC, designed for demanding surface-mount applications. This 20-pin QSOP package integrates 19 resistors, each with a 33.2KΩ resistance value and a tight 0.5% tolerance, ensuring exceptional accuracy. The network operates over a wide temperature range (70°C to 125°C @ derated power) and features a ±25ppm/°C temperature coefficient, delivering stable performance in thermally dynamic environments. With a 1W total power rating (0.05W per resistor) and a 100V maximum voltage rating, it is engineered for reliability in precision circuits. The gull-wing termination and 0.64mm terminal pitch facilitate robust PCB mounting.

GUS-QS0B-03-3322-D Features

• High Precision: 0.5% tolerance and ±25ppm/°C TCR for minimal drift.
• Robust Construction: Thin-film technology ensures low noise and long-term stability.
• Compact Design: 8.66mm (L) × 6.02mm (D) × 1.47mm (H) QSOP package saves board space.
