GUS-QS8B-02-1801-D Description

The GUS-QS8B-02-1801-D from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding surface-mount applications. This 16-pin QSOP package integrates 15 resistors, each with a 1.8KΩ resistance value and a tight 0.5% 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 -70°C to +125°C, making it suitable for environments with thermal fluctuations. The 0.75W (3/4W) total power rating (0.05W 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-QS8B-02-1801-D Features

• Precision Thin Film Technology: Ensures low noise and high stability for sensitive analog circuits.
• Compact QSOP Package: 4.9mm (L) × 6.02mm (D) × 1.47mm (H) footprint ideal for high-density PCBs.
• High Power Handling: 0.75W total dissipation (0.05W per resistor) outperforms standard networks in similar form factors.
• Wide Temperature Range: Operates reliably from -70°C to +125°C, with derated performance up to 125°C.
• Automotive-Grade Alternatives: While not automotive-certified, its thin-film construction and ±50ppm/°C TCR make it a candidate for industrial-grade replacements.
• Non-RoHS Compliant: Suitable for legacy or exempted applications requiring leaded components.
