GUS-QS8A-02-1183-CA Description

The GUS-QS8A-02-1183-CA 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 118K Ohm resistance 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 -70°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 further enhance its reliability in power-sensitive designs.

GUS-QS8A-02-1183-CA Features

• Precision Engineering: Thin-film technology with 0.25% tolerance and ±50ppm/°C TCR for minimal drift.
• Robust Construction: QSOP package (4.9mm x 6.02mm x 1.47mm) with gull-wing terminals for secure SMD mounting.
• High Power Handling: 0.1W per resistor (0.75W total) derated up to 125°C, ideal for compact, high-density layouts.
• Isolated Design: 8 independent resistors (ISOL circuit) for flexible circuit configurations.
• Stable Performance: Operates reliably from -70°C to +125°C, suited for industrial and automotive-grade applications (though not PPAP or Automotive certified).

GUS-QS8A-02-1183-CA Applications

• Signal Processing: Precision voltage dividers in ADC/DAC circuits.
