GUS-QS8A-02-1542-CB Description

The GUS-QS8A-02-1542-CB from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding surface-mount applications. This 16-pin QSOP package integrates 8 isolated resistors, each with a 15.4KΩ resistance and an ultra-tight ±0.25% tolerance, ensuring exceptional accuracy in signal conditioning and voltage division circuits. With a ±50ppm/°C temperature coefficient, it delivers stable performance across a wide temperature range (70°C to 125°C derated, 125°C max). The 0.75W (3/4W) total power rating and 100V maximum voltage rating make it suitable for high-reliability industrial and instrumentation systems. Packaged in a tube for automated assembly, its gull-wing termination and compact dimensions (4.9mm x 6.02mm x 1.47mm) optimize PCB space efficiency.

GUS-QS8A-02-1542-CB Features

• Precision Thin Film Technology: Ensures low noise and high stability for critical analog circuits.
• Isolated Resistor Design (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 density.
• Wide Operating Range: Reliable from -55°C to +125°C (derated above 70°C).
• QSOP Package: 0.64mm terminal pitch and 1.63mm seated height enable high-density layouts.
• Automotive-Grade Alternatives: While this model is not PPAP/automotive certified, its robustness suits industrial equivalents.
