GUS-QS8A-03-2491-GA Description

The GUS-QS8A-03-2491-GA is a high-performance 8-resistor thin-film network from TT Electronics/IRC, designed for precision applications requiring stable resistance values and low temperature coefficients. This 16-pin QSOP (Quarter Small Outline Package) device features a 2.49KΩ resistance per resistor with a tight 2% tolerance and an ultra-low ±25ppm/°C temperature coefficient, ensuring minimal drift across its 70°C to 125°C operating range. With a 0.75W (3/4W) total power rating and 0.1W per resistor, it delivers reliable performance in compact, space-constrained designs. The gull-wing termination and surface-mount (SMD) configuration facilitate automated assembly, while its 100V maximum voltage rating makes it suitable for moderate-voltage circuits.

GUS-QS8A-03-2491-GA Features

• Precision Thin-Film Technology: Offers superior stability, low noise, and high accuracy compared to thick-film alternatives.
• Compact QSOP Package: Measures just 4.9mm (L) x 6.02mm (D) x 1.47mm (H), ideal for high-density PCB layouts.
• Isolated Resistor Network (ISOL): Each resistor operates independently, enhancing design flexibility.
• Wide Temperature Range: Operates reliably from -55°C to +125°C (derated above 70°C).
• Robust Power Handling: 0.75W total dissipation with 0.1W per resistor, balancing performance and thermal management.
• Automation-Friendly: 0.64mm terminal pitch and gull-wing leads ensure compatibility with pick-and-place systems.
