GUS-QS8A-03-6810-GG Description

The GUS-QS8A-03-6810-GG is a high-performance thin-film resistor network from TT Electronics/IRC, designed for precision applications in demanding electronic circuits. This 8-resistor isolated network features a 681Ω resistance value per resistor with a tight 2% tolerance and an ultra-stable ±25ppm/°C temperature coefficient, ensuring reliable performance across a wide temperature range of 70°C to 125°C. Housed in a compact 16-pin QSOP (QSOP-16) package, it offers a 0.75W (3/4W) total power rating (0.1W per resistor) and supports 100V maximum voltage, making it ideal for space-constrained, high-density PCB designs. The gull-wing termination ensures secure surface-mount (SMD) assembly, while its thin-film technology provides superior accuracy and long-term stability compared to thick-film alternatives.

GUS-QS8A-03-6810-GG Features

• Precision Thin Film Technology: Delivers low noise, high stability, and tight tolerance (±2%) for critical analog/digital circuits.
• High Power Density: 0.75W total power (0.1W per resistor) in a miniature 4.9mm × 6.02mm × 1.47mm footprint, optimizing board space.
• Wide Temperature Range: Operates reliably from 70°C to 125°C with derated power, suited for industrial and automotive environments (though not PPAP/AEC-Q200 qualified).
• Isolated Circuit Design (ISOL): Each resistor is electrically independent, enabling flexible circuit configurations.
• Robust Construction: QSOP package with gull-wing leads ensures mechanical durability and ease of automated assembly.
• Non-RoHS Compliant: Suitable for legacy or exempted applications requiring leaded components.
