GUS-QS8A-02-3242-CA Description

The GUS-QS8A-02-3242-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 32.4KΩ resistance, a tight 0.25% tolerance, and a low ±50ppm/°C temperature coefficient. With a 0.75W (3/4W) total power rating and 0.1W per resistor, it operates reliably across a wide temperature range of 70°C to 125°C (derated) and up to 125°C maximum. Its 100V maximum voltage rating and gull-wing termination ensure robust performance in compact PCB layouts.

GUS-QS8A-02-3242-CA Features

• Precision Thin Film Technology: Delivers stable, low-noise performance with ±50ppm/°C thermal stability.
• High Power Density: 0.75W total power in a compact 4.9mm × 6.02mm × 1.47mm QSOP package.
• Isolated Resistors (ISOL): Eight independent 32.4KΩ resistors for flexible circuit design.
• Automotive-Grade Alternatives: While not automotive-qualified (PPAP: No), its reliability suits industrial and telecom applications.
• RoHS Non-Compliant: Note for legacy systems requiring leaded components.
