GUS-QS8A-03-1133-BB Description

The GUS-QS8A-03-1133-BB 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 113KΩ resistance value and an ultra-tight 0.1% 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 (0.1W per resistor) and 100V maximum voltage rating provide robust handling of moderate power loads while maintaining reliability.

GUS-QS8A-03-1133-BB Features

• Precision Thin Film Technology: Delivers low noise and high stability for sensitive analog circuits.
• Isolated Resistor Design (ISOL): Each of the 8 resistors operates independently, reducing crosstalk in multi-channel systems.
• Compact QSOP Package: Measures 4.9mm (L) × 6.02mm (D) × 1.47mm (H) with a 0.64mm terminal pitch, ideal for space-constrained PCB layouts.
• Gull Wing Termination: Ensures reliable solder joints in automated SMT assembly processes.
• Extended Temperature Range: Operates reliably from -70°C to +125°C, outperforming standard commercial-grade networks.
• High Power Density: 0.75W total dissipation in a miniature footprint, reducing board space versus discrete resistors.
