GUS-QS8A-03-2740-BB Description

The GUS-QS8A-03-2740-BB is a high-precision thin-film resistor network from TT Electronics/IRC, designed for demanding surface-mount (SMD) applications. This 16-pin QSOP package integrates 8 isolated resistors, each with a 274 Ω resistance and an ultra-tight 0.1% tolerance, ensuring exceptional accuracy in signal conditioning and voltage division circuits. With a ±25 ppm/°C temperature coefficient, it delivers stable performance across a wide temperature range (70°C to 125°C). The 0.75W (3/4W) total power rating (0.1W per resistor) and 100V maximum voltage rating make it suitable for high-reliability environments. Its gull-wing termination and compact dimensions (4.9mm x 6.02mm x 1.47mm) enable efficient PCB space utilization.

GUS-QS8A-03-2740-BB Features

• Precision Thin Film Technology: Ensures low noise, high stability, and minimal drift over time.
• Isolated Resistor Design (ISOL): Each of the 8 resistors operates independently, ideal for multi-channel isolation.
• High Power Handling: 0.75W total dissipation (0.1W per resistor) with derating up to 125°C.
• Ultra-Low Tolerance (0.1%): Critical for precision analog circuits, DAC/ADC interfaces, and feedback networks.
• Robust Construction: QSOP package with gull-wing leads for reliable surface-mount assembly.
• Wide Operating Range: -55°C to +125°C (full power up to 70°C).
• Non-Automotive/Non-PPAP: Optimized for industrial, medical, and instrumentation applications.

GUS-QS8A-03-2740-BB Applications
