GUS-QS8A-03-3160-CA Description

The GUS-QS8A-03-3160-CA from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding surface-mount applications. This 16-pin QSOP package features 8 isolated resistors, each with a 316Ω resistance value and an ultra-tight ±0.25% tolerance, ensuring exceptional accuracy in signal conditioning and voltage division circuits. With a ±25ppm/°C temperature coefficient, it delivers stable performance across a wide temperature range of -70°C to +125°C, making it suitable for harsh environments. The 0.75W (3/4W) total power rating (0.1W per resistor) and 100V maximum voltage rating provide robust handling of moderate power loads. Its gull-wing termination and 0.64mm terminal pitch facilitate reliable PCB mounting in space-constrained designs.

GUS-QS8A-03-3160-CA Features

• Precision Thin Film Technology: Ensures low noise and high stability for sensitive analog circuits.
• Isolated Resistor Configuration (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), optimizing board space.
• High Power Density: 0.75W total dissipation in a miniature footprint outperforms similar arrays.
• Wide Operating Range: Reliable from -70°C to +125°C, with derated power at elevated temperatures.
• RoHS Non-Compliant: Suitable for legacy or specialized applications requiring non-RoHS materials.
