GUS-QS8A-02-3740-GA Description

The GUS-QS8A-02-3740-GA from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications. This 16-pin QSOP (Quarter Small Outline Package) device features 8 isolated resistors, each with a 374Ω resistance value and a tight 2% tolerance. With a power rating of 0.75W (3/4W) and a ±50ppm/°C temperature coefficient, it ensures stable performance across a wide temperature range of 70°C to 125°C. The gull-wing termination and surface-mount design make it ideal for automated assembly processes. Encased in a rectangular QSOP package (4.9mm x 6.02mm x 1.47mm), it offers a compact footprint while maintaining high reliability.

GUS-QS8A-02-3740-GA Features

• Precision Thin-Film Technology: Delivers excellent stability and low noise.
• Isolated Resistors (ISOL): Each of the 8 resistors operates independently, enhancing design flexibility.
• High Power Handling: 0.1W per resistor and 0.75W total power dissipation for robust performance.
• Wide Operating Range: Rated for -55°C to +125°C, with derated power up to 125°C.
• Low TCR (±50ppm/°C): Minimizes resistance drift under thermal stress.
• Compact QSOP Package: Saves board space while supporting 0.64mm terminal pitch for high-density layouts.
• Gull-Wing SMD Termination: Ensures reliable solder joints and compatibility with reflow processes.
