GUS-QS8A-03-1331-DB Description

The GUS-QS8A-03-1331-DB is a high-precision thin-film resistor network from TT Electronics/IRC, designed for demanding surface-mount applications. This 16-pin QSOP package integrates 8 isolated resistors, each with a 1.33KΩ resistance and a tight 0.5% tolerance, ensuring exceptional accuracy in signal conditioning and voltage division circuits. With a 0.75W (3/4W) total power rating and ±25ppm/°C temperature coefficient, it delivers stable performance across a wide temperature range (70°C to 125°C derated, 125°C max). The gull-wing termination and 0.64mm terminal pitch facilitate reliable PCB mounting, while its compact 4.9mm × 6.02mm × 1.47mm footprint suits space-constrained designs.

GUS-QS8A-03-1331-DB Features

• Precision Thin Film Technology: Offers low noise and high stability for sensitive analog circuits.
• Isolated Resistors (ISOL): Each of the 8 resistors operates independently, ideal for multi-channel isolation.
• High Power Handling: 0.1W per resistor (0.75W total) outperforms standard networks in power dissipation.
• Wide Voltage Rating: Supports up to 100V, suitable for industrial and instrumentation use.
• Robust Construction: QSOP package with gull-wing leads ensures mechanical durability and solderability.
• Non-Automotive Grade: Optimized for commercial/industrial applications where PPAP compliance is not required.
