GUS-QS0B-03-2322-FA Description

The GUS-QS0B-03-2322-FA from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications. This 20-pin QSOP (Quarter Small Outline Package) device integrates 19 resistors, each with a 23.2KΩ resistance value and a tight 1% tolerance, ensuring consistent performance in demanding circuits. With a ±25ppm/°C temperature coefficient, it delivers exceptional stability across a wide operating temperature range of 70°C to 125°C. The 1W total power rating (0.05W per resistor) and 100V maximum voltage rating make it suitable for high-reliability designs. Its gull-wing termination and surface-mount (SMD) configuration facilitate easy PCB integration, while the tube packaging ensures safe handling and storage.

GUS-QS0B-03-2322-FA Features

• Precision Thin Film Technology: Offers low noise and high stability for sensitive analog and digital circuits.
• Compact QSOP Package: Measures 8.66mm (L) x 6.02mm (D) x 1.47mm (H) with tight tolerances (±0.1mm L/H, ±0.2mm D), ideal for space-constrained designs.
• High Power Handling: 1W total dissipation (1/20W per resistor) outperforms similar networks in power density.
• Wide Temperature Range: Operates reliably from 70°C to 125°C with derated power, suited for industrial and automotive environments (though not PPAP/automotive certified).
• Low TCR (±25ppm/°C): Minimizes resistance drift under thermal stress, critical for precision voltage dividers and feedback networks.
• Gull-Wing SMD Termination: Ensures robust solder joints and compatibility with automated assembly processes.
