GUS-QS8A-01-8451-GF Description

The GUS-QS8A-01-8451-GF from TT Electronics/IRC is a high-performance 8-resistor thin-film network designed for precision applications. It features an 8.45KΩ resistance value per resistor with a tight 2% tolerance and a low ±100ppm/°C temperature coefficient, ensuring stable performance across a wide temperature range of 70°C to 125°C. Housed in a 16-pin QSOP package with gull-wing SMD termination, this resistor network is optimized for surface-mount assembly in compact PCB designs. Its isolated (ISOL) circuit design allows independent resistor operation, making it ideal for applications requiring individual resistor control. With a 0.75W (3/4W) total power rating and 100V maximum voltage rating, it balances power handling with space efficiency.

GUS-QS8A-01-8451-GF Features

• Thin-film technology: Delivers high precision and stability.
• 8 isolated resistors: Independent functionality for flexible circuit design.
• Compact QSOP package: 4.9mm (L) × 6.02mm (D) × 1.47mm (H) footprint saves board space.
• Gull-wing termination: Ensures reliable solder joints for SMT processes.
• Wide operating range: -55°C to +125°C with derated power up to 125°C.
• Robust power handling: 0.1W per resistor (0.75W total) suits medium-power applications.
• Low TCR (±100ppm/°C): Minimizes resistance drift under thermal stress.
