GUS-QS8A-02-1210-GC Description

The GUS-QS8A-02-1210-GC 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 121Ω resistance value per resistor with a tight 2% tolerance and a low ±50ppm/°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 and 0.1W (1/10W) per resistor, making it suitable for space-constrained designs requiring reliable power dissipation. The gull-wing termination ensures secure surface-mount attachment, while the 100V maximum voltage rating enhances durability in demanding circuits.

GUS-QS8A-02-1210-GC Features

• Precision Thin-Film Technology: Delivers high accuracy (±2%) and low TCR (±50ppm/°C) for stable performance.
• Compact QSOP-16 Package: Measures just 4.9mm (L) × 6.02mm (D) × 1.47mm (H), ideal for dense PCB layouts.
• Isolated Resistor Network (ISOL): Each of the 8 resistors is electrically isolated, providing design flexibility.
• Robust Power Handling: 0.75W total power (0.1W per resistor) supports moderate power applications.
• Wide Temperature Range: Operates reliably from 70°C to 125°C with derated power performance.
• Gull-Wing SMD Termination: Ensures strong solder joints for automated assembly processes.
• 100V Maximum Voltage Rating: Suitable for industrial and telecom applications requiring higher voltage tolerance.
