GUS-QS8A-03-4750-GF Description

The GUS-QS8A-03-4750-GF from TT Electronics/IRC is a high-performance 8-resistor thin-film network designed for precision applications. Encased in a 16-pin QSOP package with gull-wing SMD termination, this device offers a 475Ω resistance per element with a tight 2% tolerance and an ultra-stable ±25ppm/°C temperature coefficient. Its isolated (ISOL) circuit design ensures independent resistor functionality, making it ideal for signal conditioning, voltage division, and impedance matching. With a 0.75W (3/4W) total power rating (0.1W per resistor) and a 100V maximum voltage rating, it operates reliably across a 70°C to 125°C derated power range, peaking at 125°C maximum operating temperature. The compact 4.9mm × 6.02mm × 1.47mm footprint and 0.64mm terminal pitch facilitate high-density PCB layouts.

GUS-QS8A-03-4750-GF Features

• Precision Thin Film Technology: Delivers low noise, high stability, and repeatable performance in harsh environments.
• Isolated Resistor Network: Each of the 8 resistors operates independently, eliminating crosstalk for critical analog circuits.
• Robust Power Handling: 0.75W total dissipation (0.1W per resistor) with derating up to 125°C, outperforming standard arrays.
• Space-Efficient QSOP Package: 16-pin gull-wing SMD design ensures compatibility with automated assembly processes.
• Wide Voltage Range: Supports up to 100V, suitable for industrial and instrumentation applications.
• Non-Automotive/Non-PPAP: Optimized for commercial and industrial use where PPAP compliance isn’t required.
