GUS-QS8A-02-6650-CA Description

The GUS-QS8A-02-6650-CA is a high-precision thin-film resistor network from TT Electronics/IRC, designed for demanding surface-mount applications. This 16-pin QSOP package features 8 isolated resistors, each with a 665Ω resistance value and an ultra-tight ±0.25% tolerance, ensuring exceptional accuracy in signal conditioning and voltage division circuits. With a ±50ppm/°C temperature coefficient, it delivers stable performance across a wide operating range of -55°C to +125°C, making it suitable for environments with thermal fluctuations. The 0.75W (3/4W) total power rating and 100V maximum voltage rating provide robust handling of moderate power loads, while the gull-wing termination ensures reliable solder joints in automated PCB assembly.

GUS-QS8A-02-6650-CA Features

• Precision Thin Film Technology: Delivers 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), saving board space in dense layouts.
• High Power Handling: 0.1W per resistor (0.75W total) outperforms standard networks in power dissipation.
• Wide Temperature Range: Operates reliably from -55°C to +125°C, with derated performance up to 125°C.
• Automated Assembly-Friendly: 0.64mm terminal pitch and gull-wing leads optimize pick-and-place efficiency.
