GUS-QS8A-02-2670-BB Description

The GUS-QS8A-02-2670-BB is a high-precision 8-resistor thin-film network from TT Electronics/IRC, designed for demanding surface-mount applications. Encased in a 16-pin QSOP package with gull-wing terminations, it offers a 267Ω resistance per element with an ultra-tight 0.1% tolerance and a low ±50ppm/°C temperature coefficient. The network operates over a wide temperature range (-70°C to +125°C) and delivers a total power rating of 0.75W (3/4W), with 0.1W per resistor, ensuring reliability in high-density circuits. Its isolated (ISOL) circuit design provides flexibility for complex configurations, while the 100V maximum voltage rating enhances safety in signal conditioning and voltage division tasks.

GUS-QS8A-02-2670-BB Features

• Precision Performance: Thin-film technology ensures low noise, high stability, and minimal drift over temperature.
• Robust Construction: QSOP package (4.9mm × 6.02mm × 1.47mm) with 0.64mm pitch enables compact PCB layouts.
• High Power Handling: 0.75W total dissipation (0.1W per resistor) outperforms standard networks in power-intensive applications.
• Wide Operating Range: Functions reliably from -70°C to +125°C, suitable for industrial and automotive environments (though not PPAP/automotive-certified).
• Isolated Design: Independent resistors allow versatile circuit integration without shared node limitations.
