GUS-QS8A-03-9762-CB Description

The GUS-QS8A-03-9762-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 97.6KΩ resistance, a tight ±0.25% tolerance, and a low ±25ppm/°C temperature coefficient. Rated for 0.75W (3/4W) total power and 0.1W per resistor, it operates reliably across a wide temperature range of -55°C to +125°C, with derated performance up to 125°C. Its 100V maximum voltage rating and gull-wing termination ensure robust performance in compact PCB layouts. The isolated (ISOL) circuit design enhances signal integrity, making it ideal for precision analog and mixed-signal circuits.

GUS-QS8A-03-9762-CB Features

• High Precision: 0.25% tolerance and ±25ppm/°C TCR for stable performance in temperature-varying environments.
• Compact & Robust: QSOP package (4.9mm x 6.02mm x 1.47mm) with 0.64mm pitch, suitable for high-density designs.
• Isolated Resistors: 8 independent 97.6KΩ resistors prevent crosstalk, critical for signal conditioning.
• Power Efficiency: 0.75W total power dissipation (0.1W per resistor) balances performance and thermal management.
• Thin-Film Technology: Delivers low noise, high stability, and long-term reliability compared to thick-film alternatives.
• Surface-Mount Ready: Gull-wing terminals facilitate automated assembly and reflow soldering.
