GUS-QS8A-03-1691-DA Description

The GUS-QS8A-03-1691-DA from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding electronic applications. This 16-pin QSOP (Quarter Small Outline Package) device features 8 isolated resistors, each with a 1.69 kΩ resistance value and a tight ±0.5% tolerance, ensuring exceptional accuracy. With a ±25 ppm/°C temperature coefficient, it delivers stable performance across a wide temperature range of -70°C to +125°C. The 0.75W (3/4W) total power rating (0.1W per resistor) and 100V maximum voltage rating make it suitable for high-reliability circuits. Its gull-wing termination and surface-mount design facilitate easy PCB integration.

GUS-QS8A-03-1691-DA Features

• Precision Thin Film Technology: Ensures low noise, high stability, and minimal drift.
• Compact QSOP Package: Measures just 4.9mm (L) × 6.02mm (D) × 1.47mm (H), ideal for space-constrained designs.
• Isolated Resistors (ISOL): Each of the 8 resistors operates independently, enhancing design flexibility.
• Robust Performance: Operates reliably at derated power up to 125°C, suited for industrial environments.
• High Power Density: 0.75W total dissipation in a small footprint outperforms similar networks.
• Strict Tolerance & TCR: ±0.5% tolerance and ±25 ppm/°C ensure precision in critical applications.
