GUS-QS8A-03-1133-DA Description

The GUS-QS8A-03-1133-DA 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 113KΩ resistance, offering a tight ±0.5% tolerance and a low ±25ppm/°C temperature coefficient. With a 0.75W (3/4W) total power rating and 0.1W per resistor, it operates reliably across a wide temperature range of -70°C to +125°C, making it suitable for harsh environments. The gull-wing termination ensures secure PCB mounting, while the compact 4.9mm x 6.02mm footprint and 1.47mm profile optimize space efficiency.

GUS-QS8A-03-1133-DA Features

• Precision Performance: Thin-film technology ensures low noise, high stability, and minimal resistance drift over time.
• Robust Construction: 100V maximum voltage rating and derated power up to 125°C enhance reliability in high-stress conditions.
• Space-Saving Design: QSOP package with 0.64mm terminal pitch accommodates high-density layouts.
• Isolated Resistors: Independent 8-resistor network (ISOL circuit designator) eliminates crosstalk, ideal for signal isolation.
• Industrial-Grade: Non-automotive but suited for industrial, medical, and telecom applications requiring long-term precision.
