GUS-QS8A-03-1471-FB Description

The GUS-QS8A-03-1471-FB from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications. This 16-pin QSOP package features 8 isolated resistors, each with a 1.47KΩ resistance, 1% tolerance, and a ±25ppm/°C temperature coefficient, ensuring stability across a wide operating temperature range of 70°C to 125°C. With a 0.75W (3/4W) total power rating and 0.1W per resistor, it delivers reliable performance in compact, surface-mount designs. The gull-wing termination and 0.64mm terminal pitch facilitate easy PCB integration, while its 100V maximum voltage rating makes it suitable for moderate-voltage circuits.

GUS-QS8A-03-1471-FB Features

• Precision Thin Film Technology: Ensures low noise, high accuracy, and excellent thermal stability.
• Isolated Resistors (ISOL): Each of the 8 resistors operates independently, ideal for multi-channel isolation.
• Robust Power Handling: 0.75W total power dissipation with derating up to 125°C.
• Compact QSOP Package: 4.9mm (L) × 6.02mm (D) × 1.47mm (H) footprint, optimized for space-constrained designs.
• Automotive & Industrial Durability: Though not PPAP or automotive-rated, its 125°C max operating temperature suits harsh environments.
• Non-RoHS Compliant: May be preferred for legacy or specialized applications requiring non-compliant materials.
