GUS-QS8A-03-5490-DA Description

The GUS-QS8A-03-5490-DA from TT Electronics/IRC is a high-precision 8-resistor isolated network designed for demanding surface-mount applications. Featuring a 549 Ω resistance per element with a tight 0.5% tolerance and a low ±25 ppm/°C temperature coefficient, this thin-film resistor network ensures stable performance across a wide temperature range of 70°C to 125°C. Housed in a compact 16-pin QSOP package with gull-wing terminations, it offers a 0.75W (3/4W) total power rating and 0.1W per resistor, making it ideal for space-constrained, high-reliability circuits. Its 100V maximum voltage rating and isolated (ISOL) circuit design enhance signal integrity in noise-sensitive environments.

GUS-QS8A-03-5490-DA Features

• Precision Thin Film Technology: Delivers ±25 ppm/°C TCR and 0.5% tolerance for consistent performance.
• Robust Construction: QSOP package (4.9mm × 6.02mm × 1.47mm) with 0.64mm terminal pitch for high-density PCB layouts.
• High Power Handling: 0.75W total dissipation (0.1W per resistor) at 125°C max operating temperature.
• Isolated Design (ISOL): Each resistor is electrically independent, reducing crosstalk in multi-channel systems.
• Gull-Wing Termination: Ensures reliable surface-mount (SMD) soldering for automated assembly.
• Non-Automotive/Non-PPAP: Suitable for industrial, telecom, and instrumentation applications.
