GUS-QS8A-03-1472-FB Description

The GUS-QS8A-03-1472-FB is a high-performance thin-film resistor network from TT Electronics/IRC, designed for precision applications requiring stable resistance and tight tolerances. This 16-pin QSOP surface-mount device features 8 isolated resistors, each with a 14.7KΩ resistance value and a 1% tolerance, ensuring consistent performance in demanding circuits. With a 0.75W (3/4W) total power rating and ±25ppm/°C temperature coefficient, it delivers excellent thermal stability across a wide operating range of -70°C to +125°C. 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-03-1472-FB Features

• Precision Thin Film Technology: Ensures low noise, high accuracy, and long-term reliability.
• Isolated Resistor Configuration (ISOL): Each of the 8 resistors operates independently, ideal for signal isolation.
• High Power Handling: 0.1W per resistor (0.75W total) with derating up to 125°C.
• Stable Thermal Performance: ±25ppm/°C TCR minimizes resistance drift under temperature fluctuations.
• Robust Construction: QSOP package with gull-wing leads for mechanical durability and solderability.
