GUS-QS0B-03-9531-DB Description

The GUS-QS0B-03-9531-DB from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding surface-mount applications. This 20-pin QSOP package integrates 19 resistors, each with a 9.53KΩ resistance value and an ultra-tight 0.5% tolerance, ensuring exceptional accuracy in signal conditioning and voltage division circuits. The network operates over a wide temperature range of 70°C to 125°C (derated) with a ±25ppm/°C temperature coefficient, delivering stable performance in thermally challenging environments. Rated for 1W total power dissipation (0.05W per resistor) and 100V maximum voltage, it combines reliability with compactness, housed in a 6.02mm x 8.66mm rectangular QSOP case with gull-wing leads for secure PCB mounting.

GUS-QS0B-03-9531-DB Features

• Precision Thin Film Technology: Ensures low noise and high stability for sensitive analog circuits.
• High Power Density: 1W total rating in a compact QSOP package, ideal for space-constrained designs.
• Robust Thermal Performance: Operates up to 125°C with derating, suited for industrial and instrumentation use.
• Tight Tolerance & TCR: 0.5% tolerance and ±25ppm/°C TCR minimize drift in precision applications.
• Automated Assembly Friendly: Gull-wing termination and 0.64mm pitch enable reliable SMT placement.
• Non-Automotive/Non-PPAP: Optimized for commercial and industrial sectors where PPAP compliance isn’t required.
