GUS-QS8A-02-2551-GA Description

The GUS-QS8A-02-2551-GA from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications. This 8-resistor isolated network features a 2.55KΩ resistance value per resistor with a tight 2% tolerance and a low ±50ppm/°C temperature coefficient, ensuring stable performance across a wide temperature range of 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 (1/10W) per resistor, making it suitable for space-constrained, high-density PCB designs. The gull-wing termination ensures reliable surface-mount (SMD) assembly, while its 100V maximum voltage rating enhances durability in demanding circuits.

GUS-QS8A-02-2551-GA Features

• Precision Thin Film Technology: Delivers superior accuracy and stability (±50ppm/°C) compared to thick-film alternatives.
• Isolated Resistor Network (ISOL): Each resistor operates independently, ideal for signal isolation or multi-channel applications.
• Compact QSOP Package: Measures just 4.9mm (L) × 6.02mm (D) × 1.47mm (H), optimizing board space.
• High Power Handling: 0.75W total dissipation (0.1W per resistor) outperforms similar networks in its class.
• Wide Temperature Range: Operates reliably from -55°C to +125°C (derated above 70°C).
• Robust Construction: Gull-wing leads and 100V rating ensure mechanical and electrical resilience.
