GUS-QS8A-01-1243-GA Description

The GUS-QS8A-01-1243-GA from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications in surface-mount PCB assemblies. This 16-pin QSOP package integrates 8 isolated resistors, each with a 124KΩ resistance value and a tight 2% tolerance, ensuring reliable signal conditioning and voltage division. With a 0.75W (3/4W) total power rating and 0.1W per resistor, it operates efficiently across a wide temperature range of 70°C to 125°C (derated) and up to 125°C maximum. The ±100ppm/°C temperature coefficient guarantees stability in fluctuating thermal environments, while the 100V maximum voltage rating suits medium-voltage circuits. Packaged in a tube for automated assembly, its gull-wing termination ensures robust solder joints.

GUS-QS8A-01-1243-GA Features

• Precision Thin Film Technology: Delivers low noise and high accuracy (±2%) for sensitive analog/digital circuits.
• Isolated Resistors (ISOL): Eight independent 124KΩ resistors prevent crosstalk in multi-channel designs.
• Compact QSOP Package: Measures 4.9mm (L) × 6.02mm (D) × 1.47mm (H) with a 0.64mm terminal pitch, ideal for space-constrained layouts.
• High Power Handling: 0.75W total dissipation (0.1W per resistor) outperforms standard networks in power density.
• Wide Thermal Range: Stable performance from 70°C to 125°C with derating, critical for industrial/automotive environments (though not PPAP/Automotive certified).
• Gull-Wing SMT Termination: Ensures reliable PCB mounting and vibration resistance.
