GUS-QS8A-03-5900-BB Description

The GUS-QS8A-03-5900-BB from TT Electronics/IRC is a high-precision 8-resistor thin film network designed for demanding surface-mount applications. Featuring a 590Ω resistance per element with an ultra-tight 0.1% tolerance and a low ±25ppm/°C temperature coefficient, this component ensures exceptional stability and accuracy in critical circuits. Housed in a compact 16-pin QSOP package with gull wing terminations, it offers a 0.75W (3/4W) total power rating (0.1W per resistor) and operates reliably across a wide temperature range of -55°C to +125°C (derated up to 125°C). Its isolated (ISOL) circuit design and 100V maximum voltage rating make it ideal for precision analog and digital systems.

GUS-QS8A-03-5900-BB Features

• High Precision: 0.1% tolerance and ±25ppm/°C TCR for minimal drift.
• Robust Construction: Thin film technology ensures long-term reliability and low noise.
• Compact Form Factor: 4.9mm (L) × 6.02mm (D) × 1.47mm (H) QSOP package saves PCB space.
• Isolated Resistors: Independent elements (ISOL) prevent cross-talk in sensitive circuits.
• Wide Operating Range: -55°C to +125°C with derated power up to 125°C.
• Automated Assembly Friendly: Gull wing leads and 0.64mm pitch enable high-speed SMD placement.
• Non-Automotive/Non-PPAP: Suitable for industrial and commercial applications.
