GUS-QS8A-03-9532-BB Description

The GUS-QS8A-03-9532-BB is a high-precision 8-resistor thin film network from TT Electronics/IRC, designed for demanding surface-mount applications. Encased in a compact 16-pin QSOP package with gull wing termination, it offers 95.3KΩ resistance per resistor with an ultra-tight 0.1% tolerance and a low ±25ppm/°C temperature coefficient, ensuring stability across a wide operating range of -70°C to +125°C. The isolated (ISOL) circuit design provides independent resistors, making it ideal for precision voltage division or signal conditioning. With a 0.75W total power rating (0.1W per resistor) and 100V maximum voltage rating, it balances performance and reliability in space-constrained designs.

GUS-QS8A-03-9532-BB Features

• Precision Thin Film Technology: Delivers low noise and high stability for critical analog circuits.
• Compact QSOP Package: Measures just 4.9mm (L) × 6.02mm (D) × 1.47mm (H), optimizing PCB space.
• High Power Density: 0.75W total dissipation (3/4W) in a miniature footprint, outperforming similar arrays.
• Isolated Resistors: Independent 95.3KΩ resistors enable flexible circuit configurations without crosstalk.
• Wide Temperature Range: Operates reliably from -70°C to +125°C with derated power at elevated temperatures.
