GUS-QS8A-03-1070-CC Description

The GUS-QS8A-03-1070-CC from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding surface-mount applications. This 8-resistor isolated network features a 107Ω resistance value per resistor with an ultra-tight ±0.25% tolerance and a low ±25ppm/°C temperature coefficient, ensuring stable performance across a wide operating 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 precision analog and digital circuits.

GUS-QS8A-03-1070-CC Features

• High Precision: ±0.25% tolerance and ±25ppm/°C TCR for minimal drift in critical applications.
• Robust Construction: Thin-film technology ensures long-term reliability and low noise.
• Space-Saving Design: Compact 4.9mm (L) × 6.02mm (D) × 1.47mm (H) QSOP package with 0.64mm terminal pitch for high-density PCB layouts.
• Isolated Configuration (ISOL): Independent resistors reduce crosstalk in multi-channel systems.
• Wide Temperature Range: Derated power operation up to 125°C, suitable for industrial and automotive environments (though not PPAP/automotive-certified).
• Gull Wing Termination: Ensures reliable surface-mount soldering and mechanical stability.
