GUS-QS8A-01-4990-JB Description

The GUS-QS8A-01-4990-JB from TT Electronics/IRC is a high-performance 8-resistor thin-film network designed for precision applications in surface-mount circuits. Encased in a 16-pin QSOP package with gull-wing terminations, this 499Ω, 5% tolerance array delivers a 0.75W (3/4W) total power rating and ±100ppm/°C temperature coefficient, ensuring stability across a 70°C to 125°C derated power range. Its isolated (ISOL) circuit design allows independent resistor operation, while the thin-film technology guarantees low noise and high accuracy. With a 100V maximum voltage rating and 0.64mm terminal pitch, it suits densely populated PCBs. Packaged in a tube, it’s optimized for automated assembly.

GUS-QS8A-01-4990-JB Features

• High Power Handling: 0.1W per resistor (0.75W total) outperforms standard networks in power dissipation.
• Precision Thin Film: ±100ppm/°C TCR and 5% tolerance ensure reliable performance in thermal-variable environments.
• Compact & Robust: 4.9mm (L) × 6.02mm (D) × 1.47mm (H) QSOP package with 1.63mm seated height saves space without compromising durability.
• Isolated Design: Independent resistors (ISOL) enable flexible circuit configurations, unlike bussed networks.
• Automation-Ready: Gull-wing leads and tube packaging streamline pick-and-place processes.
• Wide Temp Range: Operates from -55°C to +125°C, derated to 70°C–125°C for sustained high-power use.
