GUS-QS0B-02-2871-DB Description

The GUS-QS0B-02-2871-DB from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding electronic applications. It features 19 resistors in a 20-pin QSOP package with a 2.87KΩ resistance value and an ultra-tight 0.5% tolerance. The network operates over a wide temperature range (70°C to 125°C derated, 125°C max) with a low ±50ppm/°C temperature coefficient, ensuring stability in fluctuating thermal conditions. Its 1W total power rating (0.05W per resistor) and 100V maximum voltage rating make it suitable for precision analog and digital circuits. The gull-wing termination and surface-mount design facilitate automated PCB assembly, while the tube packaging ensures safe handling and storage.

GUS-QS0B-02-2871-DB Features

• Precision Thin Film Technology: Delivers high accuracy (±0.5%) and low TCR (±50ppm/°C) for stable performance.
• Robust Construction: QSOP package (8.66mm x 6.02mm x 1.47mm) with tight dimensional tolerances (±0.1mm height, ±0.2mm depth).
• High Power Handling: 1W total dissipation (0.05W per resistor) supports energy-efficient designs.
• Wide Operating Range: Rated for -55°C to +125°C, ideal for industrial and automotive-adjacent applications (though not PPAP/Automotive certified).
• Gull-Wing SMT Termination: Ensures reliable solder joints and compatibility with high-speed pick-and-place systems.
• Non-RoHS Compliant: Suitable for legacy or exempted applications requiring leaded components.
