GUS-QS8A-02-2800-BB Description

The GUS-QS8A-02-2800-BB from TT Electronics/IRC is a high-precision 8-resistor isolated network designed for demanding surface-mount applications. This 280Ω thin-film resistor array offers a tight tolerance of ±0.1% and a low temperature coefficient of ±50ppm/°C, ensuring stable performance across a wide operating temperature range of 70°C to 125°C. Housed in a compact 16-pin QSOP package with gull-wing terminations, it features a 0.75W (3/4W) total power rating (0.1W per resistor) and a maximum voltage rating of 100V. Its isolated (ISOL) circuit design allows independent resistor operation, making it ideal for precision analog and digital circuits.

GUS-QS8A-02-2800-BB Features

• Precision Thin Film Technology: Delivers high accuracy (±0.1%) and low TCR (±50ppm/°C) for stable performance.
• Compact QSOP Package: Measures 4.9mm (L) × 6.02mm (D) × 1.47mm (H), optimizing PCB space in dense layouts.
