GUS-QS8B-03-1072-C Description

The GUS-QS8B-03-1072-C is a high-precision thin-film resistor network from TT Electronics/IRC, designed for demanding surface-mount applications. This 16-pin QSOP package integrates 15 resistors, each with a 10.7KΩ resistance 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 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.

GUS-QS8B-03-1072-C Features

• Precision Thin Film Technology: Ensures low noise and high stability for sensitive analog circuits.
• Compact QSOP Package: Measures 4.9mm (L) × 6.02mm (D) × 1.47mm (H) with ±0.1mm length/height tolerances, ideal for space-constrained PCB designs.
• Gull Wing Termination: Facilitates reliable surface-mount (SMD) soldering with a 0.64mm terminal pitch.
• High Power Density: 0.75W total dissipation (15 resistors) in a miniature footprint outperforms similar networks in power handling.
• Extended Temperature Range: Operates reliably up to 125°C, suitable for industrial and automotive-adjacent applications (though not PPAP/AEC-Q200 certified).
• Non-RoHS Compliant: Preferred for legacy or specialized systems requiring leaded soldering processes.
