GUS-QS8A-03-6341-JA Description

The GUS-QS8A-03-6341-JA from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications in surface-mount PCB assemblies. This 8-resistor isolated network features a 6.34KΩ resistance value per resistor with a 5% tolerance and a low ±25ppm/°C temperature coefficient, ensuring stable performance across a wide temperature range of -70°C to +125°C. Packaged in a 16-pin QSOP (Quarter-Small Outline Package) with gull-wing terminations, it offers a compact footprint (4.9mm x 6.02mm x 1.47mm) and a 0.64mm terminal pitch, making it ideal for space-constrained designs. With a 0.1W power rating per resistor and a total power dissipation of 0.75W, it balances efficiency and reliability in demanding circuits.

GUS-QS8A-03-6341-JA Features

• Precision Thin Film Technology: Delivers superior stability, low noise, and tight TCR (±25ppm/°C) for critical analog/digital circuits.
• High-Density QSOP Package: Space-saving 16-pin gull-wing SMD design with a 1.63mm seated height, compatible with automated assembly.
• Isolated Circuit Design (ISOL): Each resistor is electrically independent, enabling flexible circuit configurations.
• Robust Power Handling: 0.75W total power rating (0.1W per resistor) and 100V maximum voltage rating for reliable operation in harsh environments.
• Wide Temperature Range: Operates from -70°C to +125°C (derated power), suitable for industrial and automotive-grade applications (though not PPAP/automotive-certified).

GUS-QS8A-03-6341-JA Applications
