GUS-QS8A-02-4750-CB Description

The GUS-QS8A-02-4750-CB from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding surface-mount applications. This 16-pin QSOP package integrates 8 isolated resistors, each with a 475 Ω resistance value and an ultra-tight ±0.25% tolerance. The device operates over a wide temperature range of 70°C to 125°C (derated) and delivers a total power rating of 0.75W (3/4W), with 0.1W (1/10W) per resistor. Its ±50ppm/°C temperature coefficient ensures stability in thermally dynamic environments, while the 100V maximum voltage rating and gull-wing termination enable reliable performance in compact PCB layouts.

GUS-QS8A-02-4750-CB Features

• Precision Thin Film Technology: Offers low noise, high stability, and excellent TCR performance.
• Isolated Resistor Network (ISOL): Each of the 8 resistors operates independently, ideal for multi-channel isolation.
• Compact QSOP Package: Measures just 4.9mm (L) × 6.02mm (D) × 1.47mm (H), with a 0.64mm terminal pitch for high-density designs.
• Robust Power Handling: 0.75W total dissipation (0.1W per resistor) supports sustained operation at elevated temperatures.
• Automotive-Grade Alternatives: While not automotive-qualified (PPAP: No), its performance suits industrial and instrumentation applications.
• Non-RoHS Compliance: Suitable for legacy or specialized systems requiring non-compliant materials.
