GUS-QS8A-02-6191-FB Description

The GUS-QS8A-02-6191-FB from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications. This 8-resistor isolated network features a 6.19KΩ resistance value with a tight 1% tolerance and a low ±50ppm/°C temperature coefficient, ensuring stable performance across a wide temperature range (70°C to 125°C). Housed in a compact 16-pin QSOP package, it offers a 0.75W (3/4W) total power rating and 0.1W per resistor, making it suitable for high-density PCB designs. The gull-wing termination and 0.64mm terminal pitch facilitate reliable surface-mount assembly, while its 100V maximum voltage rating enhances durability in demanding circuits.

GUS-QS8A-02-6191-FB Features

• Precision Thin Film Technology: Delivers excellent stability and low noise for sensitive analog/digital circuits.
• Isolated Resistor Design (ISOL): Each resistor operates independently, reducing crosstalk in multi-channel systems.
• Compact QSOP Package: Measures just 4.9mm (L) × 6.02mm (D) × 1.47mm (H), ideal for space-constrained applications.
• High Power Handling: 0.75W total dissipation with derated performance up to 125°C.
• Robust Construction: Gull-wing leads and 100V rating ensure reliability in industrial environments.
• Non-Automotive Grade: Optimized for commercial and industrial use (PPAP not required).
